rust-graph

Simple directed graph data structure

Why?

To learn some rust. I read about people saying that implementing tree-like structures in Rust was harder than in other languages, so I decided to try one to learn some Rust.

Quickstart

[WIP]

// TODO

To-Do's

• Make Node's generic
• Implement depth-first search
• Document shortest_path implementation more
• Add edge operations (modifying/removing/...)

Implementation details

The graph is implemented as 2 arrays. One for the nodes and one for the edges.

Node removal is performed as:

1. Remove node from node array. The empty space in the array is filled with the last node in the node array, this making the operation O(1).
2. Remove all the edges point to/from the removed array.
3. Modify the edges that were previously pointing to the last array and make them point to the new location.
