Struct ethers_middleware::gas_oracle::polygon::Polygon

pub struct Polygon { /* private fields */ }

The Polygon gas station API Queries over HTTP and implements the GasOracle trait.

Implementations

impl Polygon

pub fn new(chain: Chain) -> Result<Self>

pub fn with_client(client: Client, chain: Chain) -> Result<Self>

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 GasOracle for Polygon

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.
