Trait NextDown 

pub trait NextDown: Sized {
    type Output;

    // Required method
    fn next_down(self) -> Self::Output;
}

Steps one ULP towards negative infinity.

Required Associated Types

type Output

Returns the greatest number less than self (one ULP down). Follows the inherent next_down semantics for zeros, infinities and NaN.

Required Methods

fn next_down(self) -> Self::Output

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
