Lib.rs

Will add #[no_mangle] to the item it is applied but only in debug mode.

This is useful for use with hot-lib-reloader to conditionally expose library functions to the lib reloader only in debug mode. In release mode where a build is to be expected fully static, no additional penalty is paid.

#[no_mangle_if_debug]
fn func() {}

will expand to

#[cfg(debug_assertions)]
#[no_mangle]
fn func() {}

#[cfg(not(debug_assertions))]
fn func() {}
