Struct BlockBuilder

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>,

Source

pub fn extrinsic_inclusion_mode(&self) -> ExtrinsicInclusionMode

The extrinsic inclusion mode of the runtime for this block.

Source

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).

Source

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.

Source

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.

Source

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.
