Enum fvm_wasm_instrument::gas_metering::InstructionCost

pub enum InstructionCost {
    Fixed(u64),
    Linear(u64, NonZeroU32),
}

Dynamic costs instructions.

Variants

Fixed(u64)

Charge fixed amount per instruction.

Linear(u64, NonZeroU32)

Charge the specified amount of base miligas, plus miligas based on the last item on the stack. For memory.grow this is the number of pages. For memory.copy this is the number of bytes to copy.

Note: in order to make overflows impossible, the second (cost per unit) value must be in range 0x1 ~ 0x7fff_ffff.

Trait Implementations

impl Clone for InstructionCost

fn clone(&self) -> InstructionCost

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InstructionCost

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

Formats the value using the given formatter.

impl PartialEq for InstructionCost

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