Trait num::Zero
[−]
[src]
pub trait Zero: Add<Self, Output=Self> {
fn zero() -> Self;
fn is_zero(&self) -> bool;
}Defines an additive identity element for Self.
Required Methods
fn zero() -> Self[−]
Returns the additive identity element of Self, 0.
Laws
a + 0 = a ∀ a ∈ Self
0 + a = a ∀ a ∈ Self
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.
fn is_zero(&self) -> bool[−]
Returns true if self is equal to the additive identity.
