Struct GasOracleFiller

pub struct GasOracleFiller<C> { /* private fields */ }

Use the underlying gas tracker API of GnosisScan to populate the gas price. It returns gas price in gwei. It implements the GasOracle trait. If no Oracle URL is given, it returns no values.

Implementations

impl<C> GasOracleFiller<C>

where C: HttpRequestor + Clone,

pub fn new(client: C, url: Option<Url>) -> Self

Same as Self::new but with a custom [Client].

pub fn category(self, gas_category: GasCategory) -> Self

Sets the gas price category to be used when fetching the gas price.

pub async fn query(&self) -> Result<GasOracleResponse, TransportError>

Perform a request to the gas price API and deserialize the response.

Trait Implementations

impl<C: Clone> Clone for GasOracleFiller<C>

fn clone(&self) -> GasOracleFiller<C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C: Debug> Debug for GasOracleFiller<C>

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

Formats the value using the given formatter.

impl<N, C> TxFiller<N> for GasOracleFiller<C>

where N: Network, C: HttpRequestor + Clone,

type Fillable = GasOracleFillable

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

fn status(&self, tx: &<N as Network>::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 as Network>::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 as Network>::TransactionRequest) -> bool

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

fn finished(&self, tx: &<N as Network>::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 as Network>::TxEnvelope, FillEnvelopeError<<N as Network>::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 = Result<SendableTx<N>, RpcError<TransportErrorKind>>>

where P: Provider<N>,

Prepares and fills the transaction request with the fillable properties.

fn prepare_call( &self, tx: &mut <N as Network>::TransactionRequest, ) -> impl Send + Future<Output = Result<(), RpcError<TransportErrorKind>>>

Prepares transaction request with necessary fillers required for eth_call operations asynchronously

fn prepare_call_sync( &self, tx: &mut <N as Network>::TransactionRequest, ) -> Result<(), RpcError<TransportErrorKind>>

Prepares transaction request with necessary fillers required for eth_call operations synchronously
