Struct ethers_middleware::gas_escalator::GeometricGasPrice

pub struct GeometricGasPrice { /* fields omitted */ }

Geometrically increasing gas price.

Start with initial_price, then increase it every ‘every_secs’ seconds by a fixed coefficient. Coefficient defaults to 1.125 (12.5%), the minimum increase for Parity to replace a transaction. Coefficient can be adjusted, and there is an optional upper limit.

Implementations

impl GeometricGasPrice

pub fn new<T: Into<U256>, K: Into<u64>>(
    coefficient: f64,
    every_secs: K,
    max_price: Option<T>
) -> Self

Constructor

Note: Providing None to max_price requires giving it a type-hint, so you’ll need to call this like GeometricGasPrice::new(1.125, 60u64, None::<u64>).

Trait Implementations

impl Clone for GeometricGasPrice

fn clone(&self) -> GeometricGasPrice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GeometricGasPrice

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

impl GasEscalator for GeometricGasPrice

fn get_gas_price(&self, initial_price: U256, time_elapsed: u64) -> U256

Given the initial gas price and the time elapsed since the transaction’s first broadcast, it returns the new gas price
