Trait Nan

pub trait Nan: Encoding {
    const NAN: Self;

    // Required method
    fn is_nan(self) -> bool;
}

Floating-point representations that expose NaNs.

Required Associated Constants

const NAN: Self

A representation of NaN.

For primitive floating-point types, NaN is incomparable. Therefore, prefer the is_nan predicate over direct comparisons with NaN.

Required Methods

fn is_nan(self) -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

impl Nan for f32

const NAN: Self = NaN_f32
