Struct ChainIdFiller

pub struct ChainIdFiller(/* private fields */);

A TxFiller that populates the chain ID of a transaction.

If a chain ID is provided, it will be used for filling. If a chain ID is not provided, the filler will attempt to fetch the chain ID from the provider the first time a transaction is prepared, and will cache it for future transactions.

Transactions that already have a chain_id set by the user will not be modified.

Example

let pk: PrivateKeySigner = "0x...".parse()?;
let provider =
    ProviderBuilder::<_, _, Ethereum>::default().with_chain_id(1).wallet(pk).connect_http(url);

provider.send_transaction(TransactionRequest::default()).await;

Implementations

impl ChainIdFiller

pub fn new(chain_id: Option<ChainId>) -> Self

Create a new ChainIdFiller with an optional chain ID.

If a chain ID is provided, it will be used for filling. If a chain ID is not provided, the filler will attempt to fetch the chain ID from the provider the first time a transaction is prepared.

Trait Implementations

impl Clone for ChainIdFiller

fn clone(&self) -> ChainIdFiller

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChainIdFiller

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ChainIdFiller

fn default() -> ChainIdFiller

Returns the “default value” for a type.

impl PartialEq for ChainIdFiller

fn eq(&self, other: &ChainIdFiller) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<N: Network> TxFiller<N> for ChainIdFiller

type Fillable = u64

The properties that this filler retrieves from the RPC. to fill in the TransactionRequest.

fn status(&self, tx: &N::TransactionRequest) -> FillerControlFlow

Return a control-flow enum indicating whether the filler is ready to fill in the transaction request, or if it is missing required properties.

fn fill_sync(&self, tx: &mut SendableTx<N>)

Performs any synchronous filling. This should be called before TxFiller::prepare and TxFiller::fill to fill in any properties that can be filled synchronously.

async fn prepare<P>( &self, provider: &P, _tx: &N::TransactionRequest, ) -> TransportResult<Self::Fillable>

where P: Provider<N>,

Prepares fillable properties, potentially by making an RPC request.

async fn fill( &self, _fillable: Self::Fillable, tx: SendableTx<N>, ) -> TransportResult<SendableTx<N>>

Fills in the transaction request with the fillable properties.

fn join_with<T>(self, other: T) -> JoinFill<Self, T>

where T: TxFiller<N>,

Joins this filler with another filler to compose multiple fillers.

fn continue_filling(&self, tx: &SendableTx<N>) -> bool

Returns true if the filler should continue filling.

fn ready(&self, tx: &N::TransactionRequest) -> bool

Returns true if the filler is ready to fill in the transaction request.

fn finished(&self, tx: &N::TransactionRequest) -> bool

Returns true if the filler is finished filling in the transaction request.

fn fill_envelope( &self, fillable: Self::Fillable, tx: SendableTx<N>, ) -> impl Send + Future<Output = Result<N::TxEnvelope, FillEnvelopeError<N::TransactionRequest>>>

Fills in the transaction request and try to convert it to an envelope.

fn prepare_and_fill<P>( &self, provider: &P, tx: SendableTx<N>, ) -> impl Send + Future<Output = TransportResult<SendableTx<N>>>

where P: Provider<N>,

Prepares and fills the transaction request with the fillable properties.

fn prepare_call( &self, tx: &mut N::TransactionRequest, ) -> impl Send + Future<Output = TransportResult<()>>

Prepares transaction request with necessary fillers required for eth_call operations asynchronously

fn prepare_call_sync( &self, tx: &mut N::TransactionRequest, ) -> TransportResult<()>

Prepares transaction request with necessary fillers required for eth_call operations synchronously
