Struct StorageRouter 

pub struct StorageRouter { /* private fields */ }

Storage router - LMDB primary with optional S3 backup

Write path: LMDB first (fast), then queue S3 upload (non-blocking) Read path: LMDB first, fall back to S3 if miss

Implementations

impl StorageRouter

pub fn new(local: Arc<LmdbBlobStore>) -> Self

Create router with LMDB only

pub fn put_sync(&self, hash: Hash, data: &[u8]) -> Result<bool, StoreError>

Store data - writes to LMDB, queues S3 upload in background

pub fn get_sync(&self, hash: &Hash) -> Result<Option<Vec<u8>>, StoreError>

Get data - tries LMDB first, falls back to S3

pub fn exists(&self, hash: &Hash) -> Result<bool, StoreError>

Check if hash exists

pub fn delete_sync(&self, hash: &Hash) -> Result<bool, StoreError>

Delete data from both local and S3 stores

pub fn delete_local_only(&self, hash: &Hash) -> Result<bool, StoreError>

Delete data from local store only (don’t propagate to S3) Used for eviction where we want to keep S3 as archive

pub fn stats(&self) -> Result<LmdbStats, StoreError>

Get stats from local store

pub fn list(&self) -> Result<Vec<Hash>, StoreError>

List all hashes from local store

pub fn local_store(&self) -> Arc<LmdbBlobStore>

Get the underlying LMDB store for HashTree operations
