Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnsupportedVersion

The snapshot uses a format this runtime cannot read.

Fields

found: u32

Version carried by the rejected snapshot.

supported: u32

Version accepted by this runtime.

FingerprintMismatch

The snapshot belongs to an incompatible immutable executable graph.

Fields

expected: u64

Fingerprint of the currently bound executable runtime.

found: u64

Fingerprint carried by the rejected snapshot.

NumericPathMismatch

The checkpoint was produced by the other compile-time signal path.

Fields

expected: NumericPath

Numeric path required by the receiving runtime.

found: NumericPath

Numeric path carried by the checkpoint.

InvalidPhase

The checkpoint was captured at a frame phase that cannot be restored.

Fields

found: u8

Opaque wire phase value.

InvalidSignal

A stored signal does not satisfy its declared runtime domain.

Fields

field: &'static str

Checkpoint field that contained the invalid value.

knot: usize

Dense knot slot whose semantic contract rejected it.

domain: SignalDomain

Declared signal domain.

InvalidTimer

A timer value is outside the duration authored for its knot.

Fields

knot: usize

Dense timer knot slot.

remaining: u16

Stored remaining ticks.

max: u16

Authored timer duration.

InvalidDelayHead

A delay head is outside its immutable ring extent.

Fields

knot: usize

Dense delay knot slot.

head: u16

Stored ring head.

len: u16

Immutable ring length.

InvalidRng

The xorshift stream must never be zero.

ShapeMismatch

A mutable snapshot buffer does not fit this runtime’s bound shape.

Fields

field: &'static str

Snapshot buffer whose length differs.

expected: usize

Length required by the bound runtime.

found: usize

Length carried by the rejected snapshot.

InvalidHandleIndex

An owner-free outbox id cannot be rebuilt for this runtime.

Fields

field: &'static str

Outbox field containing the invalid dense index.

index: u16

Owner-free dense index carried by the snapshot.

len: usize

Number of valid local handles in the bound runtime.

Trait Implementations

impl Clone for RestoreError

fn clone(&self) -> RestoreError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RestoreError

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

impl Eq for RestoreError

impl Error for RestoreError

Available on crate feature std only.

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for RestoreError

fn eq(&self, other: &RestoreError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
