Implementations

impl<V: Clone> InMemoryBlockStore<V>

pub fn new() -> Self

Create an empty store.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Returns true if the store is empty.

Trait Implementations

impl<V: Clone + HasBlockId> BlockStore for InMemoryBlockStore<V>

type Block = V

The block value type stored and retrieved by this implementation.

fn get_block(&self, id: BlockId) -> Result<&V, StoreError>

Retrieve a block by its ID.

fn put_block(&mut self, block: V) -> Result<(), StoreError>

Insert or replace a block.

fn delete_block(&mut self, id: BlockId) -> Result<(), StoreError>
