MemoryStore

Struct MemoryStore 

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

In-memory object map keyed by ObjectId.

Intended to replace the legacy Odb overlay hash map in a later step.

Implementations§

Source§

impl MemoryStore

Source

pub fn new(algo: HashAlgo) -> Self

Create an empty store using algo for WritableObjectStore::write.

Trait Implementations§

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more
Source§

impl ObjectStore for MemoryStore

Source§

fn hash_algo(&self) -> HashAlgo

Hash algorithm for objects written through this store.
Source§

fn read(&self, oid: &ObjectId) -> Result<Option<Object>>

Load the full object, if present. Read more
Source§

fn read_into( &self, oid: &ObjectId, buf: &mut Vec<u8>, ) -> Result<Option<ObjectKind>>

Load object payload into buf, reusing its capacity when possible. Read more
Source§

fn read_info(&self, oid: &ObjectId) -> Result<Option<ObjectInfo>>

Object kind and size without loading the full payload. Read more
Source§

fn contains(&self, oid: &ObjectId) -> Result<bool>

Whether oid is stored in this backend (without reading the payload). Read more
Source§

fn contains_many(&self, oids: &[ObjectId]) -> Result<Vec<bool>>

Source§

fn lookup_prefix( &self, prefix: &str, limit: usize, out: &mut Vec<ObjectId>, ) -> Result<()>

Fill out with object ids whose hex form starts with prefix (case-insensitive). Read more
Source§

fn refresh(&self) -> Result<bool>

Source§

fn freshen(&self, oid: &ObjectId) -> Result<bool>
