StagerNotifier provides a way to notify the caller of the staging events.

Required Methods

fn on_cache_hit(&self, size: u64)

Notifies the caller that a cache hit occurred. size is the size of the content that was hit in the cache.

fn on_cache_miss(&self, size: u64)

Notifies the caller that a cache miss occurred. size is the size of the content that was missed in the cache.

fn on_cache_insert(&self, size: u64)

Notifies the caller that a blob or directory was inserted into the cache. size is the size of the content that was inserted into the cache.

Note: not only cache misses will trigger this event, but recoveries and recycles as well.

fn on_load_dir(&self, duration: Duration)

Notifies the caller that a directory was inserted into the cache. duration is the time it took to load the directory.

fn on_load_blob(&self, duration: Duration)

Notifies the caller that a blob was inserted into the cache. duration is the time it took to load the blob.

fn on_cache_evict(&self, size: u64)

Notifies the caller that a blob or directory was evicted from the cache. size is the size of the content that was evicted from the cache.

fn on_recycle_insert(&self, size: u64)

Notifies the caller that a blob or directory was dropped to the recycle bin. size is the size of the content that was dropped to the recycle bin.

fn on_recycle_clear(&self, size: u64)

Notifies the caller that the recycle bin was cleared. size is the size of the content that was cleared from the recycle bin.
