Trait Zero

source
pub trait Zero {
    // Required methods
    fn zero() -> Self;
    fn is_zero(&self) -> bool;
}
Expand description

Base trait for types that can be wrapped in a NotZero.

Implementors must provide a singleton object that will be used to mark empty edges in a MatrixGraph.

Note that this trait is already implemented for the base numeric types.

Required Methods§

source

fn zero() -> Self

Return the singleton object which can be used as a sentinel value.

source

fn is_zero(&self) -> bool

Return true if self is equal to the sentinel value.

Object Safety§

This trait is not object safe.
