Struct SkippedMask 

pub struct SkippedMask {
    pub address: Address,
    pub slot: U256,
    pub mask: U256,
    pub value: U256,
}

A masked write (StateUpdate::SlotMasked) that could not be applied because the target slot’s current value is unknown (not cached in either layer).

A masked write needs the slot’s current value to preserve the un-masked bits (new = (old & !mask) | (value & mask)); without it the result cannot be computed, so the write is skipped rather than applied against an assumed value. It is surfaced here so the caller can fetch+seed the slot and retry; otherwise the next read lazily fetches the true value.

Deliberately not #[non_exhaustive]: it is a stable, fully-determined leaf record routinely constructed as a struct literal in equality assertions by the test suite and downstream users testing against a returned diff.

Fields

address: Address

Contract whose storage slot the masked write targeted.

slot: U256

Storage slot key that was cold.

mask: U256

The mask that was not applied.

value: U256

The value bits that were not applied.

Trait Implementations

impl Clone for SkippedMask

fn clone(&self) -> SkippedMask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SkippedMask

impl Debug for SkippedMask

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SkippedMask

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SkippedMask

impl PartialEq for SkippedMask

fn eq(&self, other: &SkippedMask) -> 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 SkippedMask

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
