}Expand description
The Core runtime api that every Substrate runtime needs to implement.
Provided Methods§
Sourcefn version(
&self,
__runtime_api_at_param__: <Block as Block>::Hash,
) -> Result<RuntimeVersion, ApiError>
fn version( &self, __runtime_api_at_param__: <Block as Block>::Hash, ) -> Result<RuntimeVersion, ApiError>
Returns the version of the runtime.
Sourcefn execute_block(
&self,
__runtime_api_at_param__: <Block as Block>::Hash,
block: Block,
) -> Result<(), ApiError>
fn execute_block( &self, __runtime_api_at_param__: <Block as Block>::Hash, block: Block, ) -> Result<(), ApiError>
Execute the given block.

) -> Result<(), ApiError>
👎Deprecated
fn initialize_block_before_version_5( &self, __runtime_api_at_param__: <Block as Block>::Hash, header: &<Block as Block>::Header, ) -> Result<(), ApiError>
Initialize a block with the given header.
Sourcefn initialize_block(
&self,
__runtime_api_at_param__: <Block as Block>::Hash,
header: &<Block as Block>::Header,
) -> Result<ExtrinsicInclusionMode, ApiError>
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.
