Required Methods
sourcefn edge_bound(&self) -> usize
fn edge_bound(&self) -> usize
Return an upper bound of the edge indices in the graph (suitable for the size of a bitmap).
sourcefn from_index(&self, i: usize) -> Self::EdgeId
fn from_index(&self, i: usize) -> Self::EdgeId
Convert i
to an edge index. i
must be a valid value in the graph.
