James Wilson 8329990a33 v0.50.0: Integrate frame-decode, redo storage APIs and break up Error. (#2100 )

* WIP integrating new frame-decode and working out new storage APIS

* WIP: first pass adding new storage things to subxt-core

* Second pass over Address type and start impl in Subxt

* WIP new storage APIs

* WIP New storage APIs roughly completed, lots of errors still

* Remove PlainorMap enum; plain and map values now use same struct to simplify usage

* Begin 'fixing' errors

* WIP splitting errors and tidying payload/address traits

* Get subxt-core compiling

* Small fixes in subxt-core and remove metadata mod

* subxt-core: cargo check --all-targets passes

* Fix test

* WIP starting to update subxt from subxt-core changes

* WIP splitting up subxt errors into smaller variants

* WIP errors: add DispatchError errors

* Port new Storage APIs to subxt-core

* cargo check -p subxt passes

* Quick-fix errors in subxt-cli (explore subcommand)

* fmt

* Finish fixing codegen up and start fixing examples

* get Subxt examples compiling and bytes_at for constants

* Add some arcs to limit lifetimes in subxt/subxt-core storage APIs

* A little Arcing to allow more method chaining in Storage APIs, aligning with Subxt

* Update codegen test

* cargo check --all-targets passing

* cargo check --features 'unstable-light-client' passing

* clippy

* Remove unused dep in subxt

* use published frame-decode

* fix wasm-example

* Add new tx extension to fix daily tests

* Remove unused subxt_core::dynamic::DecodedValue type

* Update book to match changes

* Update docs to fix more broken bits

* Add missing docs

* fmt

* allow larger result errs for now

* Add missing alloc imports in subxt-core

* Fix doc tests and fix bug getting constant info

* Fix V14 -> Metadata transform for storage & constants

* Fix parachain example

* Fix FFI example

* BlockLength decodes t ostruct, not u128

* use fetch/iter shorthands rather than entry in most storage tests

* Fix some integration tests

* Fix Runtime codegen tests

* Expose the dynamic custom_value selecter and use in a UI test

* Update codegen metadata

* Tidy CLI storage query and support (str,str) as a storage address

* Add (str,str) as valid constant address too

* Show string tuple in constants example

* Via the magic of traits, avoid needing any clones of queries/addresses and accept references to them

README.md

subxt-historic

This create is a work in progress and currently is released only as a preview.

While subxt is a library for working at the head of a chain (submitting transactions and obtaining the current state), subxt-historic is a library for decoding blocks and state that are anywhere in a chain. To broadly summarize the differences:

Feature	subxt	subxt-historic
Block access	Head of chain	Any block in chain
Connection to chain	Light client or RPC node	Archive RPC nodes only
Transaction submission	Yes	No
Metadata compatibility	V14 and newer	Any version

Examples

See the examples folder for examples of how to use subxt-historic.
