Java classfile parser (WIP)

A java classfile parser written in Rust. Project for learning both Rust and the java classfile structure.

Idea inspired by a video by tsoding.

Instructions

1. Compile java class javac java/Main.java (Already compiled and included in git repo)
2. Build: cargo build
3. Run: ./target/debug/java-parser ./java/Main.class or cargo run -- ./java/Main.class

TODO

• Parse complete file:
  • magic;
  • minor_version;
  • major_version;
  • constant_pool_count;
  • constant_pool[constant_pool_count-1];
  • access_flags;
  • this_class;
  • super_class;
  • interfaces_count;
  • interfaces[interfaces_count];
  • fields_count;
  • fields[fields_count];
  • methods_count;
  • methods[methods_count];
  • attributes_count;
  • attributes[attributes_count];
• Command line args instead of hardcoded file
• Create basic JVM?
