Build Timestamp String Generator
build_timestamp
is a simple proc-macro for Rust to generate a const
string
with a build timestamp (in UTC), formatted with strftime
syntax.
Note: using this crate makes your build non-deterministic!
Note: using this crate requires nightly Rust
Example
// Rust2018 macro import
use build_timestamp::build_time;
// generates a `const BUILD_TIME: &str`
build_time!("%A %Y-%m-%d / %H:%M:%S");
fn main() {
println!("This is {}, built on: {}",
env!("CARGO_PKG_NAME"), BUILD_TIME);
}
Running this example will print something that looks like:
This is my_crate, built on: Saturday 2018-09-08 / 11:35:43
TODO
Features that I'd like this crate to support in the future:
- proper error handling (currently just uses
unwrap()
to panic) - ability to specify the name for the generated
const
- non-UTC timezones
If you would like to implement any of this, I welcome patches.
