* begin porting over traits; remove Config use of Hash * port over the Header bits that we need * sp_core_hashing where possible, move Verify to PairSigner, remove unused errors * tidy up Config things and move related bits into one place * fix codegen * copy Era over * move AccountId, Address, Signer to Signer trait and a pass over fixing examples * impl MultiAddress, MultiSignature, AccountId32 and add back to Config (for decoding later) * Copy over StorageKey, StorageData, StorageChangeSet * subxt core compiling with no sp_core or sp_runtime * Get examples compiling * pass over fixing tests * cargo fmt * clippy tweaks and update polkadot.rs * fix codegen docs * port over special DigestItem encoding/decoding * clippy and doc fixes * cargo fmt and example fix * more cargo fmt-ing... * substrate-extra to substrate-compat * cargo.toml comments * simplify PairSigner trait bounds * move RPC types to a separate file * fix docs * Add some tests for things and other PR feedback * bump to latest sp deps * avoid needing substrate-compat feature in a test
