Crate ferripfs_blockstore 

Blockstore implementation for ferripfs, ported from Kubo’s boxo/blockstore.

This module provides:

• Block type representing data with a CID
• CID utilities for creating and parsing content identifiers
• Blockstore trait for block storage operations
• FlatFS-backed blockstore implementation
• Caching blockstore wrapper

Structs

Block

A block of data with an associated CID.

CacheStats

Cache statistics

CachingBlockstore

Caching blockstore that wraps another blockstore with an LRU cache.

FlatFsBlockstore

FlatFS blockstore - stores blocks as files using sharding.

GcBlockstore

A blockstore wrapper that can block garbage collection.

GcGuard

Guard that blocks garbage collection.

GcWriteGuard

Guard held during garbage collection.

Enums
