Macro chek::debug_almost_equal

macro_rules! debug_almost_equal {
    ($left:expr, $right:expr $(,)?) => { ... };
    ($left:expr, $right:expr, $($msg_args:tt)+) => { ... };
}

Same as chek::almost_equal! in debug builds or release builds where the -C debug-assertions was provided to the compiler. For all other builds, vanishes without a trace.

Optionally may take an additional message to display on failure, which is formatted using standard format syntax.

Example

// These are compiled to nothing if debug_assertions are off!
chek::debug_almost_equal!(1.0f32, 1.0f32 + std::f32::EPSILON);
chek::debug_almost_equal!(3.0, 3.000005f32, "Example message");
