Provided Methods

fn gas_price( &self, ) -> impl Future<Output = Result<Uint<256, 4>, Self::Error>> + Send

where Self: LoadBlock,

Returns a suggestion for a gas price for legacy transactions.

fn blob_base_fee( &self, ) -> impl Future<Output = Result<Uint<256, 4>, Self::Error>> + Send

where Self: LoadBlock,

Returns a suggestion for a base fee for blob transactions.

fn base_fee( &self, ) -> impl Future<Output = Result<Option<Uint<256, 4>>, Self::Error>> + Send

where Self: LoadBlock,

Returns the base fee for the next block, or None before London activation.

fn suggested_priority_fee( &self, ) -> impl Future<Output = Result<Uint<256, 4>, Self::Error>> + Send

where Self: 'static,

Returns a suggestion for the priority fee (the tip)

fn fee_history( &self, block_count: u64, newest_block: BlockNumberOrTag, reward_percentiles: Option<Vec<f64>>, ) -> impl Future<Output = Result<FeeHistory, Self::Error>> + Send

Reports the fee history, for the given amount of blocks, up until the given newest block.

If reward_percentiles are provided the FeeHistory will include the approximated rewards for the requested range.

fn approximate_percentile( &self, entry: &FeeHistoryEntry<<Self::Provider as HeaderProvider>::Header>, requested_percentile: f64, ) -> u128

Approximates reward at a given percentile for a specific block Based on the configured resolution

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
