Trait FloatExt

pub trait FloatExt:
    Float
    + ConstZero
    + ConstOne
    + FloatConst
    + AddAssign {
    const HALF: Self;
    const TWO: Self;

    // Required methods
    fn from_f64(x: f64) -> Self;
    fn from_usize(n: usize) -> Self;
    fn into_usize(self) -> usize;
    fn u01x2(hash: u64) -> (ClosedOpenUnit<Self>, OpenClosedUnit<Self>);
}

Floating point types.

Required Associated Constants

const HALF: Self

0.5

const TWO: Self

2.0

Required Methods

fn from_f64(x: f64) -> Self

Converts from a f64.

fn from_usize(n: usize) -> Self

Converts from a usize.

fn into_usize(self) -> usize

Converts into a usize.

fn u01x2(hash: u64) -> (ClosedOpenUnit<Self>, OpenClosedUnit<Self>)

Generates two uniform random numbers from a random hash value.

The first is sampled from [0.0, 1.0), the second from (0.0, 1.0].

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.
