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: TxHash) -> ProviderResult<Option<TxNumber>>

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: TxNumber, ) -> ProviderResult<Option<Self::Transaction>>

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

fn transaction_by_id_unhashed( &self, id: TxNumber, ) -> ProviderResult<Option<Self::Transaction>>

Get transaction by id without computing the hash.

fn transaction_by_hash( &self, hash: TxHash, ) -> ProviderResult<Option<Self::Transaction>>

Get transaction by transaction hash.

fn transaction_by_hash_with_meta( &self, hash: TxHash, ) -> ProviderResult<Option<(Self::Transaction, TransactionMeta)>>

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

fn transaction_block(&self, id: TxNumber) -> ProviderResult<Option<BlockNumber>>

Get transaction block number

fn transactions_by_block( &self, block: BlockHashOrNumber, ) -> ProviderResult<Option<Vec<Self::Transaction>>>

Get transactions by block id.

fn transactions_by_block_range( &self, range: impl RangeBounds<BlockNumber>, ) -> ProviderResult<Vec<Vec<Self::Transaction>>>

Get transactions by block range.

fn transactions_by_tx_range( &self, range: impl RangeBounds<TxNumber>, ) -> ProviderResult<Vec<Self::Transaction>>

Get transactions by tx range.

fn senders_by_tx_range( &self, range: impl RangeBounds<TxNumber>, ) -> ProviderResult<Vec<Address>>

Get Senders from a tx range.

fn transaction_sender(&self, id: TxNumber) -> ProviderResult<Option<Address>>

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", so this trait is not object safe.
