Macro require_api 

macro_rules! require_api {
    ($major:literal, $minor:literal) => { ... };
}

Check that your code is compatible with the current Telex API version.

For pre-1.0 versions (0.x.y), this requires an exact major.minor match, since breaking changes can occur on minor version bumps.

For 1.0+ versions, this requires the same major version and that your required minor version is not newer than the library’s minor version.

Example

use telex::prelude::*;

telex::require_api!(0, 2);  // Requires API version 0.2.x

fn main() {
    telex::run(App).unwrap();
}

If the version doesn’t match, you’ll get a compile-time error with guidance on how to migrate.
