Struct sc_transaction_pool::FullChainApi

pub struct FullChainApi<Client, Block> { /* private fields */ }

The transaction pool logic for full client.

Implementations

impl<Client, Block> FullChainApi<Client, Block>

pub fn new( client: Arc<Client>, prometheus: Option<&PrometheusRegistry>, spawner: &impl SpawnEssentialNamed ) -> Self

Create new transaction pool logic.

impl<Client, Block> FullChainApi<Client, Block>where Block: BlockT, Client: ProvideRuntimeApi<Block> + BlockBackend<Block> + BlockIdTo<Block> + HeaderBackend<Block> + HeaderMetadata<Block, Error = Error> + Send + Sync + 'static, Client::Api: TaggedTransactionQueue<Block>,

pub fn validate_transaction_blocking( &self, at: &BlockId<Block>, source: TransactionSource, uxt: <<Self as ChainApi>::Block as Block>::Extrinsic ) -> Result<TransactionValidity>

Validates a transaction by calling into the runtime, same as validate_transaction but blocks the current thread when performing validation. Only implemented for FullChainApi since we can call into the runtime locally.

Trait Implementations

impl<Client, Block> ChainApi for FullChainApi<Client, Block>where Block: BlockT, Client: ProvideRuntimeApi<Block> + BlockBackend<Block> + BlockIdTo<Block> + HeaderBackend<Block> + HeaderMetadata<Block, Error = Error> + Send + Sync + 'static, Client::Api: TaggedTransactionQueue<Block>,

type Block = Block

Block type.

type Error = Error

Error type.

type ValidationFuture = Pin<Box<dyn Future<Output = Result<Result<ValidTransaction, TransactionValidityError>, Error>> + Send, Global>>

Validate transaction future.

type BodyFuture = Ready<Result<Option<Vec<<<FullChainApi<Client, Block> as ChainApi>::Block as Block>::Extrinsic, Global>>, Error>>

Body future (since block body might be remote)

fn block_body(&self, hash: Block::Hash) -> Self::BodyFuture

Returns a block body given the block.

fn validate_transaction( &self, at: &BlockId<Self::Block>, source: TransactionSource, uxt: <<Self as ChainApi>::Block as Block>::Extrinsic ) -> Self::ValidationFuture

Verify extrinsic at given block.

fn block_id_to_number( &self, at: &BlockId<Self::Block> ) -> Result<Option<NumberFor<<Self as ChainApi>::Block>>>

Returns a block number given the block id.

fn block_id_to_hash( &self, at: &BlockId<Self::Block> ) -> Result<Option<<<Self as ChainApi>::Block as Block>::Hash>>

Returns a block hash given the block id.

fn hash_and_length( &self, ex: &<<Self as ChainApi>::Block as Block>::Extrinsic ) -> (<<Self as ChainApi>::Block as Block>::Hash, usize)

Returns hash and encoding length of the extrinsic.

fn block_header( &self, hash: <Self::Block as BlockT>::Hash ) -> Result<Option<<Self::Block as BlockT>::Header>, Self::Error>

Returns a block header given the block id.

fn tree_route( &self, from: <Self::Block as BlockT>::Hash, to: <Self::Block as BlockT>::Hash ) -> Result<TreeRoute<Self::Block>, Self::Error>

Compute a tree-route between two blocks. See TreeRoute for more details.
