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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
