Struct FastGasCounter

#[repr(C)]
pub struct FastGasCounter {
    pub burnt_gas: u64,
    pub gas_limit: u64,
    pub opcode_cost: 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 following three fields must be put next to another to make sure generated gas counting code can use and adjust them. We will share counter to ensure we never miss synchronization. This could change and in such a case synchronization required between compiled WASM code and the host code. The amount of gas that was irreversibly used for contract execution.

gas_limit: u64

Hard gas limit for execution

opcode_cost: u64

Cost for one opcode. Used only by VMs preceding unc_vm.

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 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.
