Summary of Changes

Hello @Pr0methean, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new "lzma-static" feature to the project, allowing users to opt for static linking of the "liblzma" library. The default feature set has been updated to leverage this new static linking option, ensuring that LZMA compression utilizes the statically linked library by default. Additionally, the change includes a minor correction to the dependency syntax for existing "flate2" related features.

Highlights

  • New Feature: lzma-static: A new "lzma-static" feature has been added to Cargo.toml. This feature enables static linking for liblzma by depending on "liblzma/static".
  • Default Feature Update: The "default" features list has been updated to use the newly introduced "lzma-static" feature instead of the previous "lzma" feature, making static linking the default behavior for LZMA compression.
  • Dependency Syntax Correction: Corrected the dependency syntax for "flate2/zlib-rs" and "flate2/zlib" within the "deflate-flate2-zlib-rs" and "deflate-flate2-zlib" features, respectively, by adding the "dep:" prefix.

Code Review

This pull request introduces a lzma-static feature to enable static linking for liblzma, making it a default. It also updates feature syntax. My review suggests a refinement to this new feature for better consistency and clarity, by creating a single feature to control static linking for the liblzma dependency that covers all compression methods using it (lzma and xz).

jiff-02 = ["dep:jiff"]
nt-time = ["dep:nt-time"]
lzma = ["dep:liblzma"]
lzma-static = ["lzma", "liblzma/static"]

Since both the lzma and xz features depend on the liblzma crate, it would be clearer to have a single feature for controlling the static linking of this dependency. Consider renaming lzma-static to something more general like liblzma-static and have it enable both compression method features.

This would make it explicit that this feature affects the entire liblzma dependency and all features that rely on it.

Suggested change
lzma-static = ["lzma", "liblzma/static"]
liblzma-static = ["lzma", "xz", "dep:liblzma/static"]
