* First pass adding functions to get blocks and extrinsics * cargo fmt and cache block events * prefix block hash with 0x * pin streams for better ergonomics and add an example of subscribing to blocks * remove unused var * standardise on _all, _best and _finalized for different block header subs * WIP center subscribing around blocks * Remove the event filtering/subscribing stuff * clippy * we need tokio, silly clippy * add extrinsic_index() call * Update subxt/src/blocks/block_types.rs Co-authored-by: Andrew Jones <ascjones@gmail.com> Co-authored-by: Andrew Jones <ascjones@gmail.com>
