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.

EmptyPlan

The plan contains no placement rules.

EmptyRange

A rule selected no state layers.

Fields

start: usize

Inclusive invalid range start.

end: usize

Exclusive invalid range end.

RangeOutOfBounds

A rule selected state layers outside the complete layout.

Fields

start: usize

Inclusive invalid range start.

end: usize

Exclusive invalid range end.

layers: usize

Complete state-layout length.

OverlappingRange

Two rules selected the same state layer.

Fields

start: usize

Inclusive overlapping range start.

frontier: usize

End of the preceding declared range.

UnassignedLayer

No rule selected one or more state layers.

Fields

layer: usize

First state layer without a rule.

UnknownGroup

A unit-aligned rule named a nonexistent execution group.

Fields

group: usize

Missing canonical execution-group slot.

GroupLengthMismatch

A unit-aligned state range and its execution group have different lengths.

Fields

group: usize

Canonical execution-group slot.

start: usize

Inclusive state-range start.

end: usize

Exclusive state-range end.

units: usize

Execution-group unit count.

DiscontiguousSelection

This partition’s selected state ranges cannot use the contiguous state representation.

Fields

frontier: usize

End of the preceding selected range.

start: usize

Start of the next selected range.

InvalidLayout(String)

The selected state layout could not be sliced from the complete layout.

Trait Implementations

impl Clone for ArchitectureStatePartitionError

fn clone(&self) -> ArchitectureStatePartitionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArchitectureStatePartitionError

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

Formats the value using the given formatter.

impl Display for ArchitectureStatePartitionError

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

Formats the value using the given formatter.

impl Eq for ArchitectureStatePartitionError

impl Error for ArchitectureStatePartitionError

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 ArchitectureStatePartitionError

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

Equality operator ==.

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

Inequality operator !=.
