Struct BlobStore 

pub struct BlobStore { /* private fields */ }

Content-addressed LRU cache of file bytes, keyed by BLAKE3-128 and shared by every sync in the process: identical files cost one entry, and delta bases are found by the hash each engine recorded for the content its client holds. Eviction only costs efficiency — a missing base falls back to full content.

Implementations

impl BlobStore

pub fn new(budget: usize) -> Self

pub fn get(&mut self, hash: u128) -> Option<Arc<Vec<u8>>>

Fetch a blob and refresh its LRU position.

pub fn put(&mut self, hash: u128, data: Arc<Vec<u8>>)

Insert (or refresh) a blob, evicting the oldest entries past the budget. Blobs larger than the whole budget are not stored.
