Crate iroh_blobs

Blobs layer for iroh.

The crate is designed to be used from the iroh crate, which provides a high level interface, but can also be used standalone.

It implements a protocol for streaming content-addressed data transfer using BLAKE3 verified streaming.

It also provides a store interface for storage of blobs and outboards, as well as a persistent and a memory store implementation.

To implement a server, the provider module provides helpers for handling connections and individual requests given a store.

To perform get requests, the get module provides utilities to perform requests and store the result in a store, as well as a low level state machine for executing requests.

The downloader module provides a component to download blobs from multiple sources and store them in a store.
