impl<Block, Client> LocalTransactionPool for BasicPool<FullChainApi<Client, Block>, Block> where
    Block: BlockT,
    Client: ProvideRuntimeApi<Block> + BlockBackend<Block> + HeaderBackend<Block> + BlockIdTo<Block>,
    Client: Send + Sync + 'static,
    Client::Api: TaggedTransactionQueue<Block>, 

type Block = Block

Block type.

type Hash = <<FullChainApi<Client, Block> as ChainApi>::Block as Block>::Hash

Transaction hash type.

type Error = <FullChainApi<Client, Block> as ChainApi>::Error

Error type.

fn submit_local(
    &self,
    at: &BlockId<Self::Block>,
    xt: LocalTransactionFor<Self>
) -> Result<Self::Hash, Self::Error>

Submits the given local unverified transaction to the pool blocking the current thread for any necessary pre-verification. NOTE: It MUST NOT be used for transactions that originate from the network or RPC, since the validation is performed with TransactionSource::Local.

impl<PoolApi, Block> MaintainedTransactionPool for BasicPool<PoolApi, Block> where
    Block: BlockT,
    PoolApi: 'static + ChainApi<Block = Block>, 

fn maintain(
    &self,

Perform maintenance

impl<PoolApi, Block> MallocSizeOf for BasicPool<PoolApi, Block> where
    PoolApi: ChainApi<Block = Block>,
    Block: BlockT, 

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself. If T::size_of is a constant, consider implementing constant_size as well.

fn constant_size() -> Option<usize>

Used to optimize MallocSizeOf implementation for collections like Vec and HashMap to avoid iterating over them unnecessarily. The Self: Sized bound is for object safety.

Transaction hash type.

type InPoolTransaction = Transaction<TxHash<Self>, TransactionFor<Self>>

In-pool transaction type.

type Error = PoolApi::Error

Error type.

fn submit_at(
    &self,

    source: TransactionSource,
    xts: Vec<TransactionFor<Self>>
) -> PoolFuture<Vec<Result<TxHash<Self>, Self::Error>>, Self::Error>

fn submit_one(
    &self,
    at: &BlockId<Self::Block>,

fn submit_and_watch(
    &self,
    at: &BlockId<Self::Block>,
    source: TransactionSource,

) -> PoolFuture<Box<TransactionStatusStreamFor<Self>>, Self::Error>

Returns a future that import a single transaction and starts to watch their progress in the pool.

fn remove_invalid(
