Enum fuel_vm::gas::GasUnit

pub enum GasUnit {
    Atom(Word),
    Arithmetic(Word),
    ArithmeticExpensive(Word),
    RegisterWrite(Word),
    Branching(Word),
    MemoryOwnership(Word),
    MemoryWrite(Word),
    Accumulated(Word),
    Undefined,
}

Gas unit cost that embeds a unit price and operations count.

The operations count will be the argument of every variant except Accumulated, that will hold the total acumulated gas.

Implementations

impl GasUnit

pub const fn cost(&self) -> Word

Return the cost := price · N.

pub const fn unit_price(&self) -> Word

Return the price per unit.

pub const fn join(self, other: Self) -> Self

Combine two gas computations, accumulating their cost.
