Exgit.Hash behaviour (exgit v0.1.0)

Copy Markdown View Source

Behaviour for a git object-id hash function.

Implemented by Exgit.Hash.SHA1. A SHA-256 repo implementation would add a sibling module implementing this behaviour. The rest of the library dispatches through Exgit.Object.compute_sha/2 which uses SHA-1 today.
