Struct StackSubstateMetadata 

pub struct StackSubstateMetadata<'config> { /* private fields */ }

Implementations

impl<'config> StackSubstateMetadata<'config>

pub fn new(gas_limit: u64, config: &'config Config) -> Self

pub fn swallow_commit(&mut self, other: Self) -> Result<(), ExitError>

Swallow commit implements part of logic for exit_commit:

• Record opcode stipend.
• Record an explicit refund.
• Merge warmed accounts and storages

Errors

Return ExitError that is thrown by gasometer gas calculation errors.

pub fn swallow_revert(&mut self, other: &Self) -> Result<(), ExitError>

Swallow revert implements part of logic for exit_commit:

• Record opcode stipend.

Errors

Return ExitError that is thrown by gasometer gas calculation errors.

pub const fn swallow_discard(&self, _other: &Self)

Swallow revert implements part of logic for exit_commit: At the moment, it does nothing.

pub fn spit_child(&self, gas_limit: u64, is_static: bool) -> Self

pub const fn gasometer(&self) -> &Gasometer<'config>

pub const fn gasometer_mut(&mut self) -> &mut Gasometer<'config>

pub const fn is_static(&self) -> bool

pub const fn depth(&self) -> Option<usize>

pub fn access_address(&mut self, address: H160)

pub fn access_addresses<I>(&mut self, addresses: I)

where I: Iterator<Item = H160>,

pub fn access_storage(&mut self, address: H160, key: H256)

pub fn access_storages<I>(&mut self, storages: I)

where I: Iterator<Item = (H160, H256)>,

pub const fn accessed(&self) -> &Option<Accessed>

Used for gas calculation logic. It’s most significant for cold/warm gas calculation as warmed addresses spent less gas.

pub fn add_authority(&mut self, authority: H160, address: H160)

Add authority to accessed list (related to EIP-7702)

pub fn remove_authority(&mut self, authority: H160)

Remove authority from accessed list (related to EIP-7702)
