The Core runtime api that every Substrate runtime needs to implement.

Provided Methods

fn version( &self, __runtime_api_at_param__: <Block as Block>::Hash, ) -> Result<RuntimeVersion, ApiError>

Returns the version of the runtime.

fn execute_block( &self, __runtime_api_at_param__: <Block as Block>::Hash, block: Block, ) -> Result<(), ApiError>

Execute the given block.

fn initialize_block_before_version_5( &self, __runtime_api_at_param__: <Block as Block>::Hash, header: &<Block as Block>::Header, ) -> Result<(), ApiError>

👎Deprecated

Initialize a block with the given header.

fn initialize_block( &self, __runtime_api_at_param__: <Block as Block>::Hash, header: &<Block as Block>::Header, ) -> Result<ExtrinsicInclusionMode, ApiError>

Initialize a block with the given header and return the runtime executive mode.
