Struct MemoryStore 

pub struct MemoryStore<const BODY_SIZE: usize = DEFAULT_BODY_SIZE> { /* private fields */ }

In-memory chunk storage using a RwLock<HashMap>.

Uses interior mutability so ChunkPut::put(&self) works without external synchronization.

Implementations

impl<const BODY_SIZE: usize> MemoryStore<BODY_SIZE>

pub fn new() -> Self

Create an empty memory store.

pub fn from_chunks( chunks: impl IntoIterator<Item = AnyChunk<BODY_SIZE>>, ) -> Self

Build a store from a collection of chunks, keyed by address.

pub fn get(&self, address: &ChunkAddress) -> Option<AnyChunk<BODY_SIZE>>

Get a cloned chunk by address.

pub fn len(&self) -> usize

Number of stored chunks.

pub fn is_empty(&self) -> bool

Whether the store is empty.

pub fn into_chunks(self) -> HashMap<ChunkAddress, AnyChunk<BODY_SIZE>>

Consume the store and return all chunks.
