Struct web30::gas_estimator::GasTracker

pub struct GasTracker { /* private fields */ }

A struct for storing gas prices and estimating when it’s a good idea to perform some gas intensive operation

Implementations

impl GasTracker

pub fn new(size: usize) -> Self

create a new gas tracker with size internal sample size and number of samples before which it will not give an estimate

pub fn get_current_size(&self) -> usize

Returns the current number of stored gas prices

pub fn get_history(&self) -> VecDeque<GasPriceEntry>

Returns a copy of the stored gas price history

pub fn expand_history_size(&mut self, size: usize)

Increases the history size limit returns an error if the history is already larger than the input size

pub fn latest_gas_price(&self) -> Option<Uint256>

Gets the most recently stored gas price

pub async fn sample(web30: &Web3) -> Option<GasPriceEntry>

Samples Ethereum gas prices and creates a new GasPriceEntry on success If you are not running GasTracker multi-threaded, consider sample_and_update()

pub fn update(&mut self, sample: GasPriceEntry)

Updates the latest gas price and adds it to the array To obtain a sample, use GasTracker::sample(), or use sample_and_update() if you are not running the GasTracker multi-threaded

pub async fn sample_and_update(&mut self, web30: &Web3) -> Option<Uint256>

Gets the latest gas price and adds it to the array if this fails the sample is skipped, returns a gas price if one is successfully added

pub fn get_acceptable_gas_price(&self, percentage: f32) -> Option<Uint256>

Look through all the gas prices in the history range and determine the highest acceptable price to pay as provided by a user percentage

Trait Implementations

impl Clone for GasTracker

fn clone(&self) -> GasTracker

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GasTracker

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

Formats the value using the given formatter.

impl Default for GasTracker

fn default() -> GasTracker

Returns the “default value” for a type.

impl PartialEq for GasTracker

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for GasTracker
