Trait Zero
trait Zero: Sized + Add<Self, Output = Self>Defines an additive identity element for Self.
Laws
a + 0 = a ∀ a ∈ Self
0 + a = a ∀ a ∈ Self
Required Methods
fn zero() -> SelfReturns the additive identity element of
Self,0.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: &Self) -> boolReturns
trueifselfis equal to the additive identity.
Provided Methods
fn set_zero(self: &mut Self)Sets
selfto the additive identity element ofSelf,0.
