Trait num_traits::identities::Zero [−][src]
pub trait Zero: Sized + Add<Self, Output = Self> { fn zero() -> Self; fn is_zero(&self) -> bool; fn set_zero(&mut self) { ... } }
Required methods
fn zero() -> Self
[src]
Returns 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 mut
s.
fn is_zero(&self) -> bool
[src]
Returns true
if self
is equal to the additive identity.
