Trait One 

pub trait One: CtEq + Sized {
    // Required method
    fn one() -> Self;

    // Provided methods
    fn is_one(&self) -> Choice { ... }
    fn set_one(&mut self) { ... }
    fn one_like(_other: &Self) -> Self { ... }
}

One values: multiplicative identity element for Self.

Required Methods

fn one() -> Self

Returns the multiplicative identity element of Self, 1.

Provided Methods

fn is_one(&self) -> Choice

Determine if this value is equal to 1.

Returns

If one, returns Choice(1). Otherwise, returns Choice(0).

fn set_one(&mut self)

Set self to its multiplicative identity, i.e. Self::one.

fn one_like(_other: &Self) -> Self

Return the value 0 with the same precision as other.

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.
