Trait num_traits::identities::Zero[−][src]

pub trait Zero: Sized + Add<Self, Output = Self> {
    fn zero() -> Self;

    fn is_zero(&self) -> bool;
}
[−]

Defines an additive identity element for Self.

Required Methods

[−]

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.

[−]

Returns true if self is equal to the additive identity.
