Enum polkavm::GasMeteringKind

pub enum GasMeteringKind {
    Sync,
    Async,
}

The type of gas metering.

Variants

Sync

Synchronous gas metering. This will immediately abort the execution if we run out of gas.

Async

Asynchronous gas metering. Has a lower performance overhead compared to synchronous gas metering, but will only periodically and asynchronously check whether we still have gas remaining while the program is running.

With asynchronous gas metering the program can run slightly longer than it would otherwise, and the exact point when it is interrupted is not deterministic, but whether the computation as a whole finishes under a given gas limit will still be strictly enforced and deterministic.

This is only a hint, and the VM might still fall back to using synchronous gas metering if asynchronous metering is not available.

Trait Implementations

impl Clone for GasMeteringKind

fn clone(&self) -> GasMeteringKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GasMeteringKind

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

Formats the value using the given formatter.

impl PartialEq for GasMeteringKind

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