pub enum GasWallet {
    Value(OrderedHashMap<CostTokenType, i64>),
    Disabled,
}

Environment tracking the amount of gas available in a statement’s context.

Variants

Value(OrderedHashMap<CostTokenType, i64>)

A known value.

Disabled

If gas tracking is disabled, this value should be used for all the statements.

Implementations

impl GasWallet

pub fn update( &self, request: OrderedHashMap<CostTokenType, i64> ) -> Result<Self, GasWalletError>

Updates the value in the wallet by request. Can be both negative (for most libfuncs) and positive (for gas acquisition libfuncs).

Trait Implementations

impl Clone for GasWallet

fn clone(&self) -> GasWallet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GasWallet

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

Formats the value using the given formatter.

impl Display for GasWallet

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

Formats the value using the given formatter.

impl PartialEq for GasWallet

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