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>,
impl<'a, Block, C> BlockBuilder<'a, Block, C>where
Block: BlockT,
C: CallApiAt<Block> + ProvideRuntimeApi<Block> + 'a,
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.
