Struct TransactionPoolWrapper

pub struct TransactionPoolWrapper<Block, Client>(pub Box<dyn FullClientTransactionPool<Block, Client>>)
where
    Block: BlockT,
    Client: ProvideRuntimeApi<Block> + BlockBackend<Block> + HeaderBackend<Block> + BlockIdTo<Block> + HeaderMetadata<Block, Error = Error> + 'static,
    Client::Api: TaggedTransactionQueue<Block>;

The wrapper for actual object providing implementation of TransactionPool.

This wraps actual implementation of the TransactionPool, e.g. fork-aware or single-state.

impl<Block, Client> LocalTransactionPool for TransactionPoolWrapper<Block, Client>

where Block: BlockT, Client: ProvideRuntimeApi<Block> + BlockBackend<Block> + HeaderBackend<Block> + BlockIdTo<Block> + HeaderMetadata<Block, Error = Error> + '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: <Self::Block as BlockT>::Hash, 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.
