Struct StaticSortedFile 

Source 
pub struct StaticSortedFile { /* private fields */ }
Expand description

An SST file accessed through mmap or positional file reads.

Implementations§

Source§

impl StaticSortedFile

Source

pub fn open( db_path: &Path, meta: StaticSortedFileMetaData, compression: Compression, access_mode: AccessMode, ) -> Result<Self>

Opens an SST file using the configured access mode.

Only the index block is read here, and its CRC is verified. Key and value blocks stay lazy, read on demand.

Source

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).
