Struct ethers_middleware::gas_oracle::etherchain::Etherchain

pub struct Etherchain { /* private fields */ }

A client over HTTP for the Etherchain gas tracker API that implements the GasOracle trait.

Implementations

impl Etherchain

pub fn new() -> Self

Creates a new Etherchain gas price oracle.

pub fn with_client(client: Client) -> 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<Response>

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

Trait Implementations

impl Clone for Etherchain

fn clone(&self) -> Etherchain

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Etherchain

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

Formats the value using the given formatter.

impl Default for Etherchain

fn default() -> Self

Returns the “default value” for a type.

impl GasOracle for Etherchain

fn fetch<'life0, 'async_trait>( &'life0 self ) -> Pin<Box<dyn Future<Output = Result<U256>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait,

Makes an asynchronous HTTP query to the underlying GasOracle to fetch the current gas price estimate.

fn estimate_eip1559_fees<'life0, 'async_trait>( &'life0 self ) -> Pin<Box<dyn Future<Output = Result<(U256, U256)>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait,

Makes an asynchronous HTTP query to the underlying GasOracle to fetch the current max gas fee and priority gas fee estimates.
