Trait petgraph::matrix_graph::Zero

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

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

fn zero() -> Self

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

fn is_zero(&self) -> bool

Return true if self is equal to the sentinel value.

Object Safety

This trait is not object safe.
