Implementations

impl PrecompileCalls

pub fn base_gas_cost(&self) -> u64

Get the base gas cost for the precompile call.

pub fn address(&self) -> u64

Get the EVM address for this precompile call.

pub fn input_len(&self) -> Option<usize>

Maximum length of input bytes considered for the precompile call.

Trait Implementations

impl Clone for PrecompileCalls

fn clone(&self) -> PrecompileCalls

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PrecompileCalls

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

Formats the value using the given formatter.

impl Default for PrecompileCalls

fn default() -> Self

Returns the “default value” for a type.

impl From<PrecompileCalls> for Address

fn from(value: PrecompileCalls) -> Self

Converts to this type from the input type.

impl From<PrecompileCalls> for u64

fn from(value: PrecompileCalls) -> Self

Converts to this type from the input type.

impl From<PrecompileCalls> for usize

fn from(value: PrecompileCalls) -> Self

Converts to this type from the input type.

impl From<u8> for PrecompileCalls

fn from(value: u8) -> Self

Converts to this type from the input type.

impl PartialEq for PrecompileCalls

fn eq(&self, other: &PrecompileCalls) -> 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.
