Traits and a default implementation for graph indices.
| EdgeIndex | A valid edge index.
|
| GraphIndices | An iterator over a consecutive sequence of graph indices.
|
| NodeIndex | A valid node index.
|
| OptionalEdgeIndex | An edge index that can be None.
This is a hack to get a small sized Option<EdgeIndex> by storing the None variant as IndexType::max_value().
If Rust ever adds support for integer types with invalid values other than 0, this type becomes obsolete.
|
| OptionalNodeIndex | A node index that can be None.
This is a hack to get a small sized Option<NodeIndex> by storing the None variant as IndexType::max_value().
If Rust ever adds support for integer types with invalid values other than 0, this type becomes obsolete.
