FreshnessRegistry

evm_fork_cache::freshness

Struct FreshnessRegistry 

Source 
pub struct FreshnessRegistry { /* private fields */ }
Expand description

Per-address / per-slot validity classification.

A slot’s validity is resolved with the precedence slot ▸ account ▸ default: an explicit (address, slot) entry wins, else the account-level entry for address, else the registry default (Validity::Volatile unless changed via with_default).

The setters are builder-style (&mut Self) so they can be chained.

Implementations§

Source§

impl FreshnessRegistry

Source

pub fn new() -> Self

A registry whose default validity is Validity::Volatile.

Source

pub fn with_default(default: Validity) -> Self

A registry with a custom default validity for unclassified state.

Source

pub fn default_validity(&self) -> Validity

The default validity applied when neither the slot nor the account is set.

Source

pub fn pin(&mut self, addr: Address) -> &mut Self

Pin an account (Validity::Pinned).

Source

pub fn pin_slot(&mut self, addr: Address, slot: U256) -> &mut Self

Pin a single slot (Validity::Pinned).

Source

pub fn mark_volatile(&mut self, addr: Address) -> &mut Self

Mark an account Validity::Volatile.

Source

pub fn mark_volatile_slot(&mut self, addr: Address, slot: U256) -> &mut Self

Mark a single slot Validity::Volatile.

Source

pub fn valid_through(&mut self, addr: Address, n: u64) -> &mut Self

Mark an account Validity::ValidThrough block/clock n.

Source

pub fn valid_through_slot( &mut self, addr: Address, slot: U256, n: u64, ) -> &mut Self

Mark a single slot Validity::ValidThrough block/clock n.

Source

pub fn set_account(&mut self, addr: Address, validity: Validity) -> &mut Self

Set the account-level validity for addr.

Source

pub fn set_slot( &mut self, addr: Address, slot: U256, validity: Validity, ) -> &mut Self

Set the slot-level validity for (addr, slot).

Source

pub fn validity(&self, addr: Address, slot: U256) -> Validity

Resolve the validity of (addr, slot) with slot ▸ account ▸ default.

Source

pub fn is_volatile(&self, addr: Address, slot: U256, now: u64) -> bool

Whether (addr, slot) is currently volatile (subject to verification).

true for Validity::Volatile, and for Validity::ValidThrough(m) once now > m. false for Validity::Pinned and a still-valid ValidThrough (now <= m).
