Method has_change

atomic-repository/src/changestore/mod.rs:261–274

Check if a change with the given hash exists on disk. This checks both the cache and the filesystem. Note that this doesn't verify the integrity of the change file. # Arguments `hash` - The hash of the change to check # Example ```rust,ignore if store.has_change(&hash) { let change = store.load_change(&hash)?; } ```
