Struct MemoryBlockStore 

pub struct MemoryBlockStore { /* private fields */ }

Simple in-memory block store for testing and development.

Implementations

impl MemoryBlockStore

pub fn new(block_size: usize, total_blocks: u64) -> Self

pub fn stats_writes(&self) -> u64

Return the total number of write_block calls made so far.

Trait Implementations

impl BlockStore for MemoryBlockStore

fn block_size(&self) -> usize

Block size in bytes.

fn total_blocks(&self) -> u64

Total number of blocks in the store.

fn read_block(&self, block_id: u64) -> FsResult<Vec<u8>>

Read a full block. Returns exactly block_size() bytes.

fn write_block(&self, block_id: u64, data: &[u8]) -> FsResult<()>

Write a full block. data must be exactly block_size() bytes.

fn sync(&self) -> FsResult<()>

Sync / flush all writes. No-op for in-memory stores.

fn read_blocks(&self, block_ids: &[u64]) -> FsResult<Vec<Vec<u8>>>

Read multiple blocks in one call.

fn write_blocks(&self, blocks: &[(u64, &[u8])]) -> FsResult<()>

Write multiple blocks in one call.
