    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

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

Return true if self is equal to the sentinel value.
