* add new tests for #[ink(namespace = ..)] and #[ink(selector = ..)] attrs * [lang] implement new errors for ink! attributes: namespace, selector * add #[ink(extension = N: u32)] attribute * apply rustfmt * [lang] add initial implementation of chain extension proc. macro * [lang] rename AttributeArg -> AttributeFrag * rename AttributeFrag::kind field to arg * rename AttributeArgKind -> AttributeArg Also introduce a new AttributeArgKind type and AttributeArg::kind method. * [lang] apply rustfmt * add Display impl for AttributeArgKind * [lang] use AttributeArgKind in sanitize_attributes and ensure_first methods * [lang/ir] improve error reporting for duplicate ink! attributes * [lang/ir] refactoring and improvements to chain extension IR impl * [lang/ir] add tests for IR implementation of chain extensions * [lang/ir] remove some code dupe * [lang/ir] add getters to ChainExtension * [lang/ir] add re-exports for ChainExtension definitions * [lang/codegen] add initial impl for ChainExtensions * [env] add ChainExtension assoc type to the Environment trait * [lang] initial impl to make it possible to use chain extension syntax * [env] improvements to chain extensions API Also removes the unstable crate feature guarding the feature. * [lang/macro] add UI test for chain extension * [lang/macro] register new UI test * [lang/codegen] fix some codegen bugs with new chain extension feature * [lang, env] apply rustfmt * [lang/ir] apply clippy suggestions and fix outdated error messages * [lang/ir] fix some tests and incorrect error messages * [examples] apply clippy suggestion * add ErrorCode to ink! chain extension trait * add FromStatusCode trait to ink_lang * add #[ink(expect_output)] and #[ink(expect_ok)] attributes Also add their handling for the #[ink::chain_extension] proc. macro. * add ink_lang::IsResultType trait * add ChainExtensionMethodInputs iterator * hide docs for IsResultType trait * add some docs to chain extension codegen * implement expect_ok and expect_output where bounds in codegen * apply code review suggestions by (cmichi) * add ReturnCode::into_u32 getter * change return type of ext::call_chain_extension: RetCode -> u32 Chain extensions do not follow the general scheme of error return code because they have their own set of errors that is custom defined by the author of the chain extension. * [lang] add ChainExtension trait Not yet sure we need it. * change EnvBackend::call_chain_extension signature The new signature is much more low-level and supports all the different ways to call a chain extension method. This commit already implements the chain extension call on the on-chain environment. More work needs to be done to properly support this for the off-chain environment. * remove old high-level API for calling chain extension methods * [env] add new high-level module to handle chain extension calls * rename ChainExtensionMethodInstance -> ChainExtensionMethod * [env] add doc examples to chain extension method API * apply rustfmt * [env] clippy: allow complex type in ChainExtensionMethod type state * silence some warnings * re-export IsResultType from ink_lang crate * [lang] remove FromStatusCode trait This trait already exists in the ink_env crate. * [lang] update codegen for chain extensions Not yet done but close. * [lang] update simple chain extension test Compiles now again. * apply rustfmt * update some license headers * [env] fix where bound * extend chain extension test case to cover all cases * add messages for read_small, access and unlock_access * fix some bugs with chain extension method signatures in test * fix some bugs and docs in chain extension test * fix test * update quickcheck to 1.0 * [env] implement chain extension calling for off-chain env The new interface is much more lower-level and it is still impossible to use chain state from within the chain extension call. The latter must be fixed as soon as the off-chain environment receives its rework. * apply rustfmt * add docs to #[ink::chain_extension] proc. macro * rename env_types -> env everywhere * make doc examples for #[ink::chain_extension] compile * add yet another technical limitation * make link to simple.rs test case more stable (point to revision) * fix docs (code suggestion) Co-authored-by:
