Struct HashStore 

pub struct HashStore { /* private fields */ }

Thread-safe hash store using sled embedded database

Implementations

impl HashStore

pub fn new(path: &str) -> Result<Self>

Create a new HashStore at the specified path

pub fn get(&self, hash: &str) -> Result<Option<UploadedFile>>

Get an uploaded file by its hash

pub fn insert(&self, hash: &str, file: UploadedFile) -> Result<()>

Insert a new uploaded file record

pub fn insert_deferred(&self, hash: &str, file: &UploadedFile) -> Result<()>

Insert without flushing. Sled flushes on its own every half second, so a crash loses at most that much; for runs that insert many records and call flush when done.

pub fn remove_deferred(&self, hash: &str) -> Result<()>

Forget one file without flushing (see insert_deferred).

pub fn flush(&self) -> Result<()>

Write everything to disk.

pub fn open_tree(&self, name: &str) -> Result<Tree>

Another keyspace in the same database (e.g. the per-path file index), since sled lets only one process open it at a time.

pub fn remove(&self, hash: &str) -> Result<()>

Forget one file, e.g. when the image it points to no longer exists

pub fn clear(&self) -> Result<()>

Clear all entries from the cache

pub fn stats(&self) -> Result<CacheStats>

Get cache statistics

pub fn count(&self) -> Result<usize>

Get the total number of entries in the cache

pub fn size(&self) -> Result<u64>

Get the total size of cached data in bytes (sum of file_size fields)

Trait Implementations

impl Clone for HashStore

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
