Macro assert_eq_float::debug_assert_ne_float

macro_rules! debug_assert_ne_float {
    ($left:expr, $right:expr $(,)?) => { ... };
    ($left:expr, $right:expr; $($arg:tt)+) => { ... };
    ($left:expr, $right:expr, $error:expr $(,)?) => { ... };
    ($left:expr, $right:expr, $error:expr; $($arg:tt)+) => { ... };
}

Asserts that two float expressions are not (approximately) equal to each other.

Unlike assert_ne_float!, debug_assert_ne_float! statements are only enabled in non optimized builds by default. An optimized build will not execute debug_assert_ne_float! statements unless -C debug-assertions is passed to the compiler. This makes debug_assert_ne_float! useful for checks that are too expensive to be present in a release build but may be helpful during development. The result of expanding debug_assert_ne_float! is always type checked.
