Struct HashChunkDict 

pub struct HashChunkDict { /* private fields */ }

An implementation of ChunkDict based on HashMap.

Implementations

impl HashChunkDict

pub fn new(digester: Algorithm) -> Self

Create a new instance of HashChunkDict.

pub fn hashmap(&self) -> &HashMap<RafsDigest, (Arc<ChunkWrapper>, AtomicU32)>

Get an immutable reference to the internal HashMap.

pub fn from_commandline_arg( arg: &str, config: Arc<ConfigV2>, rafs_config: &RafsSuperConfig, ) -> Result<Arc<dyn ChunkDict>>

Parse commandline argument for chunk dictionary and load chunks into the dictionary.

pub fn from_bootstrap_file( path: &Path, config: Arc<ConfigV2>, rafs_config: &RafsSuperConfig, ) -> Result<Self>

Load chunks from the RAFS filesystem into the chunk dictionary.
