Implement caching for the `Issue` and `Patch` COB. This is achieved by having the `Transaction::initial` and `Transaction::commit` methods take a cache which can update the newly created/updated object. The `Store::remove` method also takes the cache for removing the object from the cache, as well as the repository. This meant that the `*Mut` types for the respective COBs are required to carry a cache alongside the repository store. Identities will not be cached, and so this is always set to `NoCache` -- which performs no caching, and always succeeds. To perform cache reading for issues and patches, the `cache::Issues` and `cache::Patches` traits are introduced. They capture the minimal amount of methods that are needed for the `rad issue` and `rad patch` CLI commands. The implementor for each of these traits is there respective `Cache` types, which combines their backing repository store and the SQLite database. They both provide convenience methods: - `create` (and `draft` for patches) - `get_mut` - `remove` which can be used instead of their repository store counterparts. All uses of the repository stores (where needed) are replaced with `Cache` types. Signed-off-by: Fintan Halpenny <fintan.halpenny@gmail.com> X-Clacks-Overhead: GNU Terry Pratchett |
