This is needed for hardware wallets, which require human confirmation to
sign transactions. Blocking on a human to sign transactions is not a
good idea, and the signing might fail for many reasons (device
unplugged, authorization not granted, etc).
* Update to substrate alpha.7
* Remove gas limit from contracts put code
* Rename SystemEvent::ReapedAccount to KilledAccount
* Log debug event received before attempting to decode
* Temporary registration of Balance type before #102 merged
* Show contract test errors, increase instantiate gas_limit
* Support custom clients.
* Simplify trait bounds.
* Plain and double map storage support.
* Simplify more trait bounds.
* Add proc macro.
* Add Call, Event and Store traits.
* Update proc-macros.
* Add with_system for proc-macro.
* proc-macro: test: support signature and extra fields.
* proc-macro: test: support sharing state accross steps.
* proc-macro: test: fetch state sequentially.
* Elide lifetimes.
* Add test for plain storage.
* Run rustfmt.
* WIP
* Begin converting rpc layer to use std futures and jsonrpsee
* Convert metadata to async/await
* Convert block_hash to async/await
* Convert more methods to async/await
* Remove sp_rpc
* Fix more compilation errors
* Remove connect
* Starting to convert subscription functions
* Use jsonrpsee branch from PR for public client types
* Implement subscribe events with jsonrpsee subscription
* Converting subscriptions and wait_for_block_events
* WIP converting lib methods to async
* Use shared client reference directly for rpc call
`rpc_api!` macro currently only supports RawClient (which cannot be shared).
Also supports named params only which is not currently compatible with substrate rpd which accepts only positional params.
* Use &self instead of &mut self for shared Client
* Convert submit_and_watch to async/await
* Convert more Client fns to async
* Pin some trait futures
* Add serde error
* Fix client creation
* Fix client request compiler errors
* Unify metadata errors
* Add WS handshake error variant
* Fix some more compiler errors
* Fix more compiler errors
* Convert submit_extrinsic to async
* Convert submit and submit_and_watch
* Add Send + Sync constraints
* Clone clients
* Fix EventArg conversion error
* Fix remaining warnings/errors
* Replace deny warnings with specific lints
* Infallable subscription loops
* Use jsonrpsee wss branch
* Fix example
* Start to fix up tests
* Make contracts tests compile
* Make some more tests pass
* Fix up remaining tests
* Fmt
* Use correct event storage key type
* Fix finding events
* Use master jsonrpsee
* Do not error if type sizes missing: log warn
* Split out EventsSubscriber, allow updating events decoder
* Format code
* Check missing type sizes after registration
* Add example which for submit and watching events
* Move contracts tests to contracts module
* Add test for instantiating a contract
* Fix InstantiateArgs encoding
* Ignore PhantomData primitives, they are 0
* Increase endowment and log code hash
* Update SystemEvent
* Fix codec import
* Oops
* Write buffer directly to output to avoid encoding vec
* Debug with StorageChanges encoded as hex
* Logging and format code
