* Adds message types * Add code skeleton * Adds subsystem code. * Adds a first test * Adds interaction result to availability_lru * Use LruCache instead of a HashMap * Whitespaces to tabs * Do not ignore errors * Change error type * Add a timeout to chunk requests * Add custom errors and log them * Adds replace_availability_recovery method * recovery_threshold computed by erasure crate * change core to std * adds docs to error type * Adds a test for invalid reconstruction * refactors interaction run into multiple methods * Cleanup AwaitedChunks * Even more fixes * Test that recovery with wrong root is an error * Break to launch another requests * Styling fixes * Add SessionIndex to API * Proper relay parents for MakeRequest * Remove validator_discovery and use message * Remove a stream on exhaustion * On cleanup free the request streams * Fix merge and refactor
