compile-time
This crate provides macros for getting compile time information.
You can get the compile time either as time::Date, time::Time,
time::OffsetDateTime, string, or UNIX timestamp.
You can get the Rust compiler version either as semver::Version or string,
and the individual version parts as integer literals or strings, respectively.
Example
let compile_datetime = datetime_str!;
let rustc_version = rustc_version_str!;
println!;
