## Graphlib

Graphlib is a simple and powerful Rust graph library.

This library attempts to provide a generic api for building, mutating and iterating over graphs that is similar to that of other data-structures found in Rust i.e. `Vec`

, `HashMap`

, `VecDeque`

, etc.

### Using Graphlib

```
use graphlib::Graph;
let mut graph: Graph<usize> = Graph::new();
// Add two vertices to the graph
let id1 = graph.add_vertex(1);
let id2 = graph.add_vertex(2);
// Add an edge between the two vertices
graph.add_edge(&id1, &id2);
assert_eq!(*graph.fetch(&id1).unwrap(), 1);
assert_eq!(*graph.fetch(&id2).unwrap(), 2);
// The graph has 2 vertices and one edge at this point
assert_eq!(graph.vertex_count(), 2);
assert_eq!(graph.edge_count(), 1);
// Remove one of the connected vertices
graph.remove(&id1);
assert_eq!(graph.vertex_count(), 1);
assert_eq!(graph.edge_count(), 0);
```

`std`

Using without In `Cargo.toml`

:

```
[dependencies]
graphlib = { version = "*", features = ["no_std"] }
```
