* 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> * Add dynbamic nested query example and make dynamic::tx a little easier to work with * calL_value -> inner_tx * rename example to dynamic_multisig to align with #713 naming * align dynamic and static multisig examples * Fix comment typo Co-authored-by: Niklas Adolfsson <niklasadolfsson1@gmail.com> Co-authored-by: Andrew Jones <ascjones@gmail.com> Co-authored-by: Niklas Adolfsson <niklasadolfsson1@gmail.com>
