}Expand description
The BlockBuilder api trait that provides the required functionality for building a block.
Provided Methods§
Sourcefn apply_extrinsic(
&self,
__runtime_api_at_param__: <Block as BlockT>::Hash,
extrinsic: <Block as BlockT>::Extrinsic,
) -> Result<ApplyExtrinsicResult, ApiError>
fn apply_extrinsic( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, extrinsic: <Block as BlockT>::Extrinsic, ) -> Result<ApplyExtrinsicResult, ApiError>
Apply the given extrinsic.
Returns an inclusion outcome which specifies if this extrinsic is included in this block or not.
fn apply_extrinsic_before_version_6( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, extrinsic: <Block as BlockT>::Extrinsic, ) -> Result<ApplyExtrinsicResult, ApiError>
👎Deprecated
Sourcefn finalize_block(
&self,
__runtime_api_at_param__: <Block as BlockT>::Hash,
) -> Result<<Block as BlockT>::Header, ApiError>
fn finalize_block( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, ) -> Result<<Block as BlockT>::Header, ApiError>
Finish the current block.
Sourcefn inherent_extrinsics(
&self,
__runtime_api_at_param__: <Block as BlockT>::Hash,
inherent: InherentData,
) -> Result<Vec<<Block as BlockT>::Extrinsic>, ApiError>
fn inherent_extrinsics( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, inherent: InherentData, ) -> Result<Vec<<Block as BlockT>::Extrinsic>, ApiError>
Generate inherent extrinsics. The inherent data will vary from chain to chain.
Sourcefn check_inherents(
&self,
__runtime_api_at_param__: <Block as BlockT>::Hash,
block: Block,
data: InherentData,
) -> Result<CheckInherentsResult, ApiError>
fn check_inherents( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, block: Block, data: InherentData, ) -> Result<CheckInherentsResult, ApiError>
Check that the inherents are valid. The inherent data will vary from chain to chain.
