Struct FastGasCounter 

#[repr(C)]
pub struct FastGasCounter {
    pub burnt_gas: u64,
    pub gas_limit: u64,
}

Fast gas counter with very simple structure, could be exposed to compiled code in the VM. For instance by intrinsifying host functions responsible for gas metering.

Fields

burnt_gas: u64

The amount of gas that was irreversibly used for contract execution.

gas_limit: u64

Hard gas limit for execution

Implementations

impl FastGasCounter

pub fn new(limit: u64) -> Self

New fast gas counter.

pub fn burnt(&self) -> u64

Amount of gas burnt, maybe load as atomic to avoid aliasing issues.

Trait Implementations

impl Clone for FastGasCounter

fn clone(&self) -> FastGasCounter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FastGasCounter

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

Formats the value using the given formatter.

impl Display for FastGasCounter

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

Formats the value using the given formatter.

impl PartialEq for FastGasCounter

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

Tests for self and other values to be equal, and is used by ==.

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

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