Crate crate_git_revision

Embed the git revision of a crate in its build.

Supports embedding the version from a local or remote git repository the build is occurring in, as well as when cargo install or depending on a crate published to crates.io.

It extracts the git revision in two ways:

• From the .cargo_vcs_info.json file embedded in published crates.
• From the git repository the build is occurring from in unpublished crates.

Injects an environment variable GIT_REVISION into the build that contains the full git revision, with a -dirty suffix if the working directory is dirty.

Requires the use of a build.rs build script. See Build Scripts for more details on how Rust build scripts work.

Examples

Add the following to the crate’s Cargo.toml file:

[build_dependencies]
crate-git-revision = "0.0.2"

Add the following to the crate’s build.rs file:

crate_git_revision::init();

Add the following to the crate’s lib.rs or main.rs file:

pub const GIT_REVISION: &str = env!("GIT_REVISION");

Functions

• init
  Initialize the GIT_REVISION environment variable with the git revision of the current crate.
