source · pub struct BlockBuilder<'a, Block: BlockT, C: ProvideRuntimeApi<Block> + 'a> { /* private fields */ }
Expand description
Utility for building new (valid) blocks from a stream of extrinsics.
Implementations§
source§impl<'a, Block, C> BlockBuilder<'a, Block, C>where
Block: BlockT,
C: CallApiAt<Block> + ProvideRuntimeApi<Block> + 'a,
C::Api: BlockBuilderApi<Block>,

C::Api: BlockBuilderApi<Block>,
sourcepub fn extrinsic_inclusion_mode(&self) -> ExtrinsicInclusionMode
pub fn extrinsic_inclusion_mode(&self) -> ExtrinsicInclusionMode
The extrinsic inclusion mode of the runtime for this block.
sourcepub fn push(&mut self, xt: <Block as BlockT>::Extrinsic) -> Result<(), Error>
pub fn push(&mut self, xt: <Block as BlockT>::Extrinsic) -> Result<(), Error>
Push onto the block’s list of extrinsics.
This will ensure the extrinsic can be validly executed (by executing it).
sourcepub fn build(self) -> Result<BuiltBlock<Block>, Error>
pub fn build(self) -> Result<BuiltBlock<Block>, Error>
Consume the builder to build a valid Block
containing all pushed extrinsics.
Returns the build Block
, the changes to the storage and an optional StorageProof
supplied by self.api
, combined as BuiltBlock
.
The storage proof will be Some(_)
when proof recording was enabled.
sourcepub fn create_inherents(
&mut self,
inherent_data: InherentData,
) -> Result<Vec<Block::Extrinsic>, Error>
pub fn create_inherents( &mut self, inherent_data: InherentData, ) -> Result<Vec<Block::Extrinsic>, Error>
Create the inherents for the block.
Returns the inherents created by the runtime or an error if something failed.
sourcepub fn estimate_block_size(&self, include_proof: bool) -> usize
pub fn estimate_block_size(&self, include_proof: bool) -> usize
Estimate the size of the block in the current state.
If include_proof
is true
, the estimated size of the storage proof will be added
to the estimation.
