Struct StorageRouter 

pub struct StorageRouter { /* private fields */ }

Storage router - local store primary with optional S3 backup

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

Implementations

impl StorageRouter

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 archives and cold tiers intact.

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

Get stats from local store

pub fn writable_stats(&self) -> Result<LocalStoreStats, StoreError>

Get stats for the writable local tier used for quota and eviction pressure.

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

List all hashes from local store

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

List hashes from the writable local tier used for quota and eviction pressure.

pub fn existing_local_hashes_in_sorted_candidates( &self, sorted_hashes: &[Hash], ) -> Result<Vec<bool>, StoreError>

Mark which sorted candidate hashes already exist in local storage.

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

Get the underlying local store for HashTree operations
