Available on crate feature provider only.

Client trait for fetching transactions related data.

Required Associated Types

type Transaction: Send + Sync + SignedTransaction

The transaction type this provider reads.

Required Methods

fn transaction_id( &self, tx_hash: FixedBytes<32>, ) -> Result<Option<u64>, ProviderError>

Get internal transaction identifier by transaction hash.

This is the inverse of TransactionsProvider::transaction_by_id. Returns None if the transaction is not found.

fn transaction_by_id( &self, id: u64, ) -> Result<Option<Self::Transaction>, ProviderError>

Get transaction by id, computes hash every time so more expensive.

fn transaction_by_id_unhashed( &self, id: u64, ) -> Result<Option<Self::Transaction>, ProviderError>

Get transaction by id without computing the hash.

fn transaction_by_hash( &self, hash: FixedBytes<32>, ) -> Result<Option<Self::Transaction>, ProviderError>

Get transaction by transaction hash.

fn transaction_by_hash_with_meta( &self, hash: FixedBytes<32>, ) -> Result<Option<(Self::Transaction, TransactionMeta)>, ProviderError>

Get transaction by transaction hash and additional metadata of the block the transaction was mined in

fn transactions_by_block( &self, block: HashOrNumber, ) -> Result<Option<Vec<Self::Transaction>>, ProviderError>

Get transactions by block id.

fn transactions_by_block_range( &self, range: impl RangeBounds<u64>, ) -> Result<Vec<Vec<Self::Transaction>>, ProviderError>

Get transactions by block range.

fn transactions_by_tx_range( &self, range: impl RangeBounds<u64>, ) -> Result<Vec<Self::Transaction>, ProviderError>

Get transactions by tx range.

fn senders_by_tx_range( &self, range: impl RangeBounds<u64>, ) -> Result<Vec<Address>, ProviderError>

Get Senders from a tx range.

fn transaction_sender(&self, id: u64) -> Result<Option<Address>, ProviderError>

Get transaction sender.

Returns None if the transaction is not found.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
