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.

EmptyLayout

A model declared no state-bearing layer slots.

EmptySegments

A composite layout declared no named state segments.

EmptySegmentId

A state segment identity was empty or whitespace-only.

EmptySegmentRange

A state segment range contained no layers.

Fields

segment: StateSegmentId

Invalid segment identity.

start: usize

Inclusive range start.

end: usize

Exclusive range end.

PositiveSegmentOffset

A state segment claimed to be ahead of the persisted token prefix.

Fields

segment: StateSegmentId

Invalid segment identity.

offset: i32

Invalid positive processed-token offset.

InvalidLayoutSlice

A requested sub-layout range was empty or outside the source layout.

Fields

start: usize

Inclusive requested layer start.

end: usize

Exclusive requested layer end.

layers: usize

Available source layer count.

DuplicateSegment

Two state segments used the same stable identity.

Fields

segment: StateSegmentId

Duplicated identity.

SegmentOutOfBounds

A state segment addressed layers outside the layout.

Fields

segment: StateSegmentId

Invalid segment identity.

start: usize

Inclusive range start.

end: usize

Exclusive range end.

layers: usize

Total layout layer count.

OverlappingSegment

A state segment overlapped an earlier segment in layer order.

Fields

segment: StateSegmentId

Overlapping segment identity.

start: usize

Inclusive range start.

frontier: usize

End of the prior segment.

UnassignedStateLayer

No named segment owned one layer in the state layout.

Fields

layer: usize

First unassigned layer.

UnknownSegment

A reset requested a segment absent from the realized layout.

Fields

segment: StateSegmentId

Requested segment identity.

ResetFailed(String)

A concrete backend failed while clearing a declared state segment.

InvalidLayer

One layer supplied an invalid portable state policy.

Fields

layer: usize

Invalid global layer index.

reason: String

Validation detail.

InvalidResidency(String)

A residency plan violates a finite-resource invariant.

UnknownLayer

A runtime requested a layer outside the realized layout.

Fields

layer: usize

Requested layer.

count: usize

Realized layer count.

UnknownComponent

A layer state does not declare the requested fixed component.

Fields

role: StateTensorRole

Requested semantic component.

InvalidAdvance(String)

A fixed-state token frontier could not be advanced safely.

Trait Implementations

impl Clone for StateError

fn clone(&self) -> StateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateError

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

Formats the value using the given formatter.

impl Display for StateError

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

impl Eq for StateError

impl Error for StateError

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

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
