Struct sc_block_builder::BlockBuilder [−][src]
Utility for building new (valid) blocks from a stream of extrinsics.
Implementations
impl<'a, Block, A, B> BlockBuilder<'a, Block, A, B> where
Block: BlockT,
A: ProvideRuntimeApi<Block> + 'a,
A::Api: BlockBuilderApi<Block, Error = Error> + ApiExt<Block, StateBackend = StateBackendFor<B, Block>>,
B: Backend<Block>,
[src]
Block: BlockT,
A: ProvideRuntimeApi<Block> + 'a,
A::Api: BlockBuilderApi<Block, Error = Error> + ApiExt<Block, StateBackend = StateBackendFor<B, Block>>,
B: Backend<Block>,
pub fn new(
api: &'a A,
parent_hash: Block::Hash,
parent_number: NumberFor<Block>,
record_proof: RecordProof,
inherent_digests: DigestFor<Block>,
backend: &'a B
) -> Result<Self, ApiErrorFor<A, Block>>
[src]
api: &'a A,
parent_hash: Block::Hash,
parent_number: NumberFor<Block>,
record_proof: RecordProof,
inherent_digests: DigestFor<Block>,
backend: &'a B
) -> Result<Self, ApiErrorFor<A, Block>>
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.
pub fn push(
&mut self,
xt: <Block as BlockT>::Extrinsic
) -> Result<(), ApiErrorFor<A, Block>>
[src]
&mut self,
xt: <Block as BlockT>::Extrinsic
) -> Result<(), ApiErrorFor<A, Block>>
Push onto the block’s list of extrinsics.
This will ensure the extrinsic can be validly executed (by executing it).
pub fn build(
self
) -> Result<BuiltBlock<Block, StateBackendFor<B, Block>>, ApiErrorFor<A, Block>>
[src]
self
) -> Result<BuiltBlock<Block, StateBackendFor<B, Block>>, ApiErrorFor<A, Block>>
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.
pub fn create_inherents(
&mut self,
inherent_data: InherentData
) -> Result<Vec<Block::Extrinsic>, ApiErrorFor<A, Block>>
[src]
&mut self,
inherent_data: InherentData
) -> Result<Vec<Block::Extrinsic>, ApiErrorFor<A, Block>>
Create the inherents for the block.
Returns the inherents created by the runtime or an error if something failed.
