pub struct StaticSortedFile { /* private fields */ }Expand description
A memory mapped SST file.
Implementations§
Source§impl StaticSortedFile
impl StaticSortedFile
Sourcepub fn open(db_path: &Path, meta: StaticSortedFileMetaData) -> Result<Self>
pub fn open(db_path: &Path, meta: StaticSortedFileMetaData) -> Result<Self>
Opens an SST file at the given path. This memory maps the file, but does not read it yet. It’s lazy read on demand.
Sourcepub fn lookup<K: QueryKey, const FIND_ALL: bool>(
&self,
key_hash: u64,
key: &K,
key_block_cache: &BlockCache,
value_block_cache: &BlockCache,
) -> Result<SstLookupResult>
pub fn lookup<K: QueryKey, const FIND_ALL: bool>( &self, key_hash: u64, key: &K, key_block_cache: &BlockCache, value_block_cache: &BlockCache, ) -> Result<SstLookupResult>
Looks up a key in this file.
If FIND_ALL is false, returns after finding the first match.
If FIND_ALL is true, returns all entries with the same key (useful for
keyspaces where keys are hashes and collisions are possible).
