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