deps(rust): bump quick-xml from 0.39.4 to 0.40.1

[dependabot]

Bumps quick-xml from 0.39.4 to 0.40.1.

Release notes

Sourced from quick-xml's releases.

v0.40.1 - Fix rarely possible serde deserialization panic

What's Changed

• #964: Fix unreachable!() panic in the serde deserializer when a DOCTYPE declaration appears between two text runs inside an element (e.g. <a>x<!DOCTYPE y>z</a>). The DOCTYPE used to break drain_text's consecutive-text merge, so two DeEvent::Text events reached read_text and tripped its "Cannot be two consequent Text events" invariant. DOCTYPE is now treated as transparent during text drain — it still goes through the entity resolver, but the surrounding text is merged into one run. Discovered via libFuzzer on a real-world SAML deserializer harness.

v0.40.0 - UTF-16 and ISO-2022-JP encodings supported

What's Changed

MSRV bumped to 1.79.

Now quick-xml supports the UTF-16 and ISO-2022-JP encoded documents. See the new DecodingReader type.

New Features

• #956: Add DecodingReader, a BufRead adapter that auto-detects encoding from BOM or XML declaration and transcodes to UTF-8. Enabled by the encoding feature.

• #938: Add new enumeration XmlVersion and typified getter BytesDecl::xml_version().

• #938: Add new error variant IllFormedError::UnknownVersion.

• #371: Add new error variant EscapeError::TooManyNestedEntities.

• #371: Improved compliance with the XML attribute value normalization process by adding

  • Attribute::normalized_value()
  • Attribute::normalized_value_with()
  • Attribute::decoded_and_normalized_value()
  • Attribute::decoded_and_normalized_value_with()

  which ought to be used in place of deprecated

  • Attribute::unescape_value()
  • Attribute::unescape_value_with()
  • Attribute::decode_and_unescape_value()
  • Attribute::decode_and_unescape_value_with()

  Deprecated functions now behaves the same as newly added.

Bug Fixes

• #938: Use correct rules for EOL normalization in Deserializer when parse XML 1.0 documents. Previously XML 1.1. rules was applied.

Misc Changes

• #914: Remove deprecated .prefixes(), .resolve(), .resolve_attribute(), and .resolve_element() of NsReader. Use .resolver().<...> methods instead.
• #938: Now BytesText::xml_content, BytesCData::xml_content and BytesRef::xml_content accepts XmlVersion parameter to apply correct EOL normalization rules.
• #944: read_text() now returns BytesText which allows you to get the content with properly normalized EOLs. To get the previous behavior use .read_text().decode()?.
• #956: Bumped MSRV from 1.59 (Feb 2022) to 1.79 (June 2024)
