Constime

This is a tiny alternative to https://github.com/nhynes/comptime-rs, with no dependencies and <80 LOC.

Usage

bash cargo add constime

Note that in order to use dependencies in comptime!, you must either: * Have it as a normal dependency in [dependencies]. * Have it as a build dependency in [build-dependencies], alongside: * A build.rs file to make rust compiles the dependencies. * Explicitly importing the crate using extern crate.

Example

```rust fn main() { use constime::comptime;

// Let's use a pure-build time dependency
println!("Here's a fact about the number 5: {}", comptime! {
    extern crate ureq;
    ureq::get("http://numbersapi.com/5/math").call().unwrap().into_string().unwrap()
});

// Standard library works fine too.
println!(
    "Compiled {} seconds after unix epoch.",
    comptime! {
        std::time::SystemTime::now()
            .duration_since(std::time::UNIX_EPOCH)
            .expect("Time went backwards")
            .as_secs()
    }
);

} ```
