Macro chek::debug_almost_zero

macro_rules! debug_almost_zero {
    ($value:expr $(,)?) => { ... };
    ($value:expr, $($msg_args:tt)+) => { ... };
}

Same as chek::almost_zero! 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_zero!(0.00000001);
chek::debug_almost_zero!(std::f32::EPSILON, "Should be almost zero!");
