[−][src]Trait num_traits::identities::Zero
Required methods
fn zero() -> Self
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
Returns true
if self
is equal to the additive identity.
Provided methods
fn set_zero(&mut self)
Sets self
to the additive identity element of Self
, 0
.
