[−][src]Struct petgraph::matrix_graph::NotZero

pub struct NotZero<T>(_);

NotZero is used to optimize the memory usage of edge weights E in a MatrixGraph, replacing the default Option<E> sentinel.

Pre-requisite: edge weight should implement Zero.

Note that if you're already using the standard non-zero types (such as NonZeroU32), you don't have to use this wrapper and can leave the default Null type argument.
