Trait libreda_db::prelude::Zero [−][src]
Required methods
pub 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.
pub fn is_zero(&self) -> bool
[src]
Returns true
if self
is equal to the additive identity.

pub fn zero() -> Vector<T>
[src]
Get zero-vector.
Examples
use iron_shapes::vector::{Vector, Zero}; let a = Vector::zero(); let b = Vector::new(0, 0); assert_eq!(a, b);
pub fn is_zero(&self) -> bool
[src]
Check if this is the zero-vector.
Examples
