Trait rin::math::One [−][src]
pub trait One: Mul<Self, Output = Self> { pub fn one() -> Self; pub fn set_one(&mut self) { ... } pub fn is_one(&self) -> bool
where
Self: PartialEq<Self>, { ... } }
Required methods
pub fn one() -> Self[src]
Returns the multiplicative identity element of Self, 1.
Purity
This function should return the same result at all times regardless of
external mutable state, for example values stored in TLS or in
static muts.
Provided methods
pub fn set_one(&mut self)[src]
Sets self to the multiplicative identity element of Self, 1.
pub fn is_one(&self) -> bool where
Self: PartialEq<Self>, [src]
Self: PartialEq<Self>,
Returns true if self is equal to the multiplicative identity.
For performance reasons, it’s best to implement this manually.
After a semver bump, this method will be required, and the
where Self: PartialEq bound will be removed.
