Bigraph

A Rust crate to represent and operate on bigraphs.

The crate defines traits as abstractions from the concrete graph implementation. At the moment, the only implementation is done via a wrapper over petgraph, which serves as a prototype.

lib.rs:

A crate to represent a bigraph. Bigraphs are graphs where each node is symmetrically mapped to a unique "mirror" node, and each edge is symmetrically mapped to a unique "mirror" edge.

Note that bigraphs come in two flavours, node- and edge-centric. A node-centric bigraph has edges that are only distinguished by their endpoints, while an edge-centric bigraph's edges are additionally distinguished by their associated data.

This crate implements a simple wrapper around the traitgraph crate, adding a vector to represent the node-mirror function. It also implements the edge-mirror function, albeit probably slower than it could be if there was also a vector to map edges.

In the context of node-centric genome graphs, nodes usually represent genome strings and a pair of mirrored nodes represent reverse complements of each other. For edge-centric genome graphs, the same holds for the edges.
