[][src]Crate build_info

Begin by adding build-info as a [dependency] and build-info-build as a [build-dependency] to your Cargo.toml. Please make sure that both dependencies use the same version!

If it does not already exist, add a build.rs to your project's root, where you call build_info_build::build_script(). This will collect build information at compile time.

Then, either use the build_info! macro to add a function that returns version information at runtime:

This example is not tested
build_info::build_info!(fn version);

or use build_info::format! to generate a string at compile time:

This example is not tested
// sample output: "{sample v0.0.13 built with rustc 1.45.0-nightly (4bd32c980 2020-05-29) at 2020-05-30 11:22:46Z}"
build_info::format!("{{{} v{} built with {} at {}}}", $.crate_info.name, $.crate_info.version, $.compiler, $.timestamp)

You can also check out the sample project that shows both variants.

Features

The ´build-info` crate has the following features:

  • runtime (enabled by default): Enables the use of build_info::build_info! and provides the prerequisite types.
  • serde (disabled by default): Adds serde support to the objects returned by build_info::build_info!. Implies the runtime feature.
  • nested (disabled by default): Enables proc-macro-nested for build_info::format!, which lets it be nested inside another proc-macro invocation in some cases.
