Struct MemObjectStore 

pub struct MemObjectStore { /* private fields */ }

In-memory object store backed by FabricHashMap.

Objects are stored as serialized entries in a hash map over leased DRAM. Large objects (>64 KiB) are split into 64 KiB chunks, each stored under a derived key (<uri>#chunk/<n>), with the root entry holding metadata and the chunk count.

Example

use grafos_store::{MemObjectStore, ObjectStore, FabricUri};

let mut store = MemObjectStore::new(64)?;
let uri: FabricUri = "fabric://p/b/k".parse()?;
store.put(&uri, b"data", None)?;
let obj = store.get(&uri)?.unwrap();
assert_eq!(obj.data, b"data");

Implementations

impl MemObjectStore

pub fn new(buckets: usize) -> Result<Self>

Create a new in-memory object store with the given number of hash map buckets.

Trait Implementations

impl ObjectStore for MemObjectStore

fn put( &mut self, uri: &FabricUri, data: &[u8], opts: Option<PutOptions>, ) -> Result<()>

Store an object at the given URI.

fn get(&self, uri: &FabricUri) -> Result<Option<ObjectData>>

Retrieve an object by URI.

fn head(&self, uri: &FabricUri) -> Result<Option<ObjectInfo>>

Retrieve object metadata without reading the data.

fn delete(&mut self, uri: &FabricUri) -> Result<bool>

Delete an object by URI. Returns true if the object existed.

fn list(&self, _pool: &str, _bucket: &str, prefix: &str) -> Result<Vec<String>>

List object keys matching a prefix within a bucket.
