refactor: move Send + Sync + 'static bounds into trait definitions

[xdustinface]

These bounds are required almost everywhere anyway, so making them explicit in the trait definitions reduces lots of repetitions.

• Add 'static to StorageManager, NetworkManager, and WalletInterface traits
• Remove redundant bounds where traits are used

Summary by CodeRabbit

• Refactor

  • Restructured trait bound requirements across core components to consolidate constraints at the trait definition level rather than impl blocks.

• Bug Fixes

  • Updated method signature in transaction handling to properly pass required parameters.

📝 Walkthrough

Walkthrough

The pull request systematically removes Send + Sync + 'static trait bounds from generic impl blocks across the codebase while simultaneously adding 'static lifetime bounds to the trait definitions themselves (WalletInterface, NetworkManager, StorageManager). One method signature is updated to accept explicit references.

Poem

🐰 Bounds relaxed in impl blocks wide,
Traits now 'static, tightened with pride,
Generics flow free, yet structured with care,
A dance of constraints—perfectly fair!

73-73: LGTM: Centralized 'static bound improves consistency.

Adding 'static to the trait definition is the right approach - it removes repetition across call sites while making the trait's lifetime requirements explicit. This aligns with the usage pattern of Arc<dyn StorageManager> mentioned in the learnings.

Optional: Enhance documentation to explain `'static` requirement

Consider adding a brief note to the documentation about the 'static bound:

 /// ## Implementation Requirements
 ///
 /// Implementations must ensure that:
+/// - The implementation is `'static` (no borrowed data with shorter lifetimes)
 /// - All operations are atomic at the logical level (e.g., all headers in a batch succeed or fail together)
 /// - Read operations are consistent (no partial reads of in-progress writes)
 /// - The implementation is safe to move between threads (`Send`)
 /// - The implementation can be referenced from multiple threads (`Sync`)

This would clarify why 'static is required (for Arc-based sharing in async contexts).

dash-spv/src/sync/filters/retry.rs (1)

15-15: LGTM! Bounds successfully moved to trait definitions.

The removal of + Send + Sync + 'static from the impl block is correct since these bounds are now enforced by the StorageManager and NetworkManager trait definitions themselves. This reduces repetition and improves maintainability.

dash-spv/src/client/sync_coordinator.rs (1)

26-26: LGTM! Simplified impl bounds are cleaner and maintain correctness.

The bounds Send + Sync + 'static are now inherited from the trait definitions (WalletInterface, NetworkManager, StorageManager), so removing them here eliminates redundancy while maintaining the same compile-time guarantees.

key-wallet-manager/src/wallet_interface.rs (1)

13-13: LGTM! Adding 'static bound is correct for trait object compatibility.

Adding 'static to the WalletInterface trait definition is appropriate given that this trait is used with Arc<dyn WalletInterface> for runtime polymorphism throughout the codebase. This change enables the removal of redundant bounds at call sites.

Note: This is a breaking change for trait implementors that aren't 'static, but this is intentional and aligns with the async/Arc<dyn> usage patterns in the codebase.

Based on learnings, the codebase uses Arc<dyn TraitName> for trait objects.

dash-spv/src/client/mempool.rs (1)

20-20: LGTM! Consistent bound simplification across client modules.

The removal of redundant bounds follows the same pattern as other client modules, successfully leveraging the 'static requirements now defined on the traits themselves.

dash-spv/src/network/mod.rs (1)

31-31: LGTM! NetworkManager trait bound updated consistently with WalletInterface.

Adding 'static to NetworkManager follows the same pattern as WalletInterface and is appropriate for a trait used with Arc<dyn NetworkManager> throughout the codebase. Verified that StorageManager already has the 'static bound and all impl blocks use simplified generic constraints without redundant trait bounds.

dash-spv/src/sync/filters/headers.rs (1)

29-29: LGTM: Redundant bounds correctly removed.

The generic bounds are now inherited from the trait definitions themselves (StorageManager and NetworkManager traits now include 'static), eliminating the need to repeat them here. This is the intended outcome of the refactoring.

dash-spv/src/sync/masternodes/manager.rs (1)

54-54: LGTM: Bounds correctly simplified.

The Send + Sync + 'static bounds are now inherited from the trait definitions, making this impl block cleaner and more maintainable.

dash-spv/src/main.rs (1)

350-350: LGTM: Function signature simplified correctly.

The bounds are now inherited from the StorageManager trait definition, making the function signature cleaner without losing any safety guarantees.

dash-spv/src/client/block_processor.rs (1)

41-41: LGTM: Impl bounds correctly streamlined.

The Send + Sync + 'static requirements are now enforced by the trait definitions (WalletInterface and StorageManager), eliminating redundancy. This is particularly important here since BlockProcessor stores these types in Arc<RwLock<W>> and Arc<Mutex<S>>, which require 'static.

dash-spv/src/sync/phase_execution.rs (1)

13-13: Clean refactoring of trait bounds.

The removal of Send + Sync + 'static bounds from the impl block is correct since these bounds are now enforced at the trait definition level for StorageManager, NetworkManager, and WalletInterface. This maintains the same guarantees while reducing repetition.

dash-spv/src/sync/manager.rs (1)

103-103: LGTM!

The impl bound simplification aligns with the trait definition changes. The struct's use of Arc<RwLock<W>> for the wallet and stats fields will continue to work correctly since the Send + Sync + 'static requirements are now encoded in the WalletInterface trait definition itself.

dash-spv/src/client/queries.rs (1)

22-22: LGTM!

The simplified bounds are appropriate for this query-focused impl block. The Send + Sync + 'static requirements are now enforced by the trait definitions, maintaining thread-safety guarantees for the underlying types.

dash-spv/src/client/status_display.rs (1)

26-26: LGTM!

The bound simplification is correct. Note that the try_get_balance_if_any helper method (line 151-175) has a local W: 'static constraint, which is now always satisfied since WalletInterface includes 'static in its trait definition. This maintains the TypeId-based downcasting functionality.

dash-spv/src/sync/filters/download.rs (1)

24-24: LGTM!

The trait bound simplification for FilterSyncManager is consistent with the PR's objective. The async filter download and verification methods will continue to work correctly as the Send + Sync + 'static requirements are now part of the StorageManager and NetworkManager trait definitions.

dash-spv/src/sync/filters/requests.rs (1)

14-14: LGTM!

The simplified impl bounds are correct. The request queue management and flow control logic remains unchanged, with Send + Sync + 'static requirements now enforced at the trait definition level.

dash-spv/src/sync/filters/stats.rs (1)

7-7: LGTM!

The bound simplification for the statistics impl block is consistent with the overall refactoring. These are simple synchronous accessor methods that don't require any changes beyond the bound relaxation.

dash-spv/src/client/transactions.rs (1)

11-11: Impl bounds correctly simplified.

The removal of + Send + Sync + 'static from the generic parameters is correct since these bounds are now part of the trait definitions themselves. This reduces repetition while maintaining the same constraints.

dash-spv/src/client/lifecycle.rs (1)

28-28: Impl bounds correctly simplified.

The relaxed bounds align with the trait-level enforcement. The async patterns (spawning tasks with tokio::spawn at line 148, using Arc<RwLock<W>> and Arc<Mutex<S>>) continue to work correctly because WalletInterface, NetworkManager, and StorageManager now include Send + Sync + 'static in their definitions.

dash-spv/src/client/message_handler.rs (1)

27-27: Impl bounds correctly simplified.

MessageHandler uses borrowed references (&'a mut) rather than owned trait objects, so the relaxed impl bounds are appropriate. The Send + Sync + 'static requirements are now enforced at the trait definition level.

dash-spv/src/client/events.rs (1)

16-16: Impl bounds correctly simplified.

The event handling methods use channel operations that don't require additional bounds beyond what the trait definitions now provide.

dash-spv/src/sync/post_sync.rs (1)

16-16: Impl bounds correctly simplified.

The post-sync handlers use mutable references to network and storage managers. The relaxed bounds are correct since StorageManager, NetworkManager, and WalletInterface traits now include the necessary bounds in their definitions.

dash-spv/src/client/progress.rs (1)

17-17: Impl bounds correctly simplified.

Progress tracking and statistics methods use standard async patterns with mutex-guarded storage access. The trait-level bounds are sufficient for these operations.

dash-spv/src/sync/headers/manager.rs (1)

64-64: Impl bounds correctly simplified.

HeaderSyncManager uses PhantomData markers for type parameters and takes mutable references to storage/network managers. The relaxed impl bounds are correct since the trait definitions now carry the Send + Sync + 'static requirements.

dash-spv/src/sync/message_handlers.rs (1)

19-19: Consistent trait bound simplification.

The impl header correctly removes redundant Send + Sync + 'static bounds on S, N, and W, relying on the trait definitions to provide these constraints.

dash-spv/src/sync/filters/matching.rs (1)

22-22: Bounds correctly simplified.

The generic bounds have been appropriately reduced to rely on the trait definitions for Send + Sync + 'static requirements.

dash-spv/src/client/core.rs (1)

149-149: Generic bounds properly simplified.

The impl block correctly removes redundant trait bounds while maintaining the same effective constraints through the trait definitions. The extensive documentation about the generic design philosophy remains accurate since the architectural approach is unchanged.

dash-spv/src/client/chainlock.rs (1)

19-19: Refactoring completed consistently.

The impl signature follows the same clean simplification pattern as the rest of the codebase, removing redundant Send + Sync + 'static bounds.

dash-spv/src/sync/filters/manager.rs (1)

89-89: Trait bound refactoring is complete and correct.

The StorageManager and NetworkManager trait definitions properly include the Send + Sync + 'static bounds, and all implementation blocks across the codebase—including FilterSyncManager, SyncManager, HeaderSyncManager, and MasternodeSyncManager—correctly reference the traits without redundant bound repetition. This approach reduces boilerplate, follows the DRY principle, and is consistent across all implementations in the codebase.
