Struct GasTracker 

pub struct GasTracker { /* private fields */ }

Tracker for gas during execution.

This is used to track the gas during execution.

Implementations

impl GasTracker

pub const fn new(gas_limit: u64, remaining: u64, reservoir: u64) -> GasTracker

Creates a new GasTracker with the given remaining gas and reservoir.

pub const fn new_used_gas( gas_limit: u64, used_gas: u64, reservoir: u64, ) -> GasTracker

Creates a new GasTracker with the given used gas and reservoir.

pub const fn limit(&self) -> u64

Returns the gas limit.

pub fn set_limit(&mut self, val: u64)

Sets the gas limit.

pub const fn remaining(&self) -> u64

Returns the remaining gas.

pub fn set_remaining(&mut self, val: u64)

Sets the remaining gas.

pub const fn reservoir(&self) -> u64

Returns the reservoir gas.

pub fn set_reservoir(&mut self, val: u64)

Sets the reservoir gas.

pub const fn state_gas_spent(&self) -> u64

Returns the state gas spent.

pub fn set_state_gas_spent(&mut self, val: u64)

Sets the state gas spent.

pub const fn refunded(&self) -> i64

Returns the refunded gas.

pub fn set_refunded(&mut self, val: i64)

Sets the refunded gas.

pub fn record_regular_cost(&mut self, cost: u64) -> bool

Records a regular gas cost.

Deducts from remaining. Returns false if insufficient gas.

pub fn record_state_cost(&mut self, cost: u64) -> bool

Records a state gas cost (EIP-8037 reservoir model).

State gas charges deduct from the reservoir first. If the reservoir is exhausted, remaining charges spill into remaining (requiring remaining >= cost). Tracks state gas spent.

Returns false if total remaining gas is insufficient.

pub fn record_refund(&mut self, refund: i64)

Records a refund value.

pub fn erase_cost(&mut self, returned: u64)

Erases a gas cost from remaining (returns gas from child frame).

pub fn spend_all(&mut self)

Spends all remaining gas excluding the reservoir.

Trait Implementations

impl Clone for GasTracker

fn clone(&self) -> GasTracker

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GasTracker

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

Formats the value using the given formatter.

impl Default for GasTracker

fn default() -> GasTracker

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for GasTracker

fn deserialize<__D>( __deserializer: __D, ) -> Result<GasTracker, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for GasTracker

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GasTracker

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

impl Serialize for GasTracker

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for GasTracker

impl Eq for GasTracker

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
