Expand description
Utility for building new (valid) blocks from a stream of extrinsics.
Implementations§
source§impl<'a, Block, A, B> BlockBuilder<'a, Block, A, B>where
Block: BlockT,
A: ProvideRuntimeApi<Block> + 'a,
A::Api: BlockBuilderApi<Block> + ApiExt<Block>,
B: Backend<Block>,
impl<'a, Block, A, B> BlockBuilder<'a, Block, A, B>where Block: BlockT, A: ProvideRuntimeApi<Block> + 'a, A::Api: BlockBuilderApi<Block> + ApiExt<Block>, B: Backend<Block>,
sourcepub fn new(
api: &'a A,
parent_hash: Block::Hash,
parent_number: NumberFor<Block>,
record_proof: RecordProof,
inherent_digests: Digest,
backend: &'a B
) -> Result<Self, Error>
pub fn new( api: &'a A, parent_hash: Block::Hash, parent_number: NumberFor<Block>, record_proof: RecordProof, inherent_digests: Digest, backend: &'a B ) -> Result<Self, Error>
Create a new instance of builder based on the given parent_hash
and parent_number
.
While proof recording is enabled, all accessed trie nodes are saved. These recorded trie nodes can be used by a third party to prove the output of this block builder without having access to the full storage.
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.
