Expand description

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

Provided Methods§

source

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

Returns the version of the runtime.

source

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

Execute the given block.

source

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.

source

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.
