Errors produced while validating or evaluating an action.

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.

ZeroDimension

A channel transform cannot target a zero-dimensional state.

EmptyPolynomial

The action omitted its transform polynomial.

EmptyMask

A present mask must contain at least one field value.

NonCanonicalFieldValue

A wire value was not a canonical field representative.

Fields

field: &'static str

Logical field containing the value.

index: usize

Index of the invalid value.

value: u64

Invalid value.

MaskDimensionMismatch

The optional projection mask did not match the channel dimension.

Fields

expected: usize

Required mask length.

actual: usize

Observed mask length.

StateDimensionMismatch

The state did not match the channel dimension.

Fields

expected: usize

Required state length.

actual: usize

Observed state length.

InvalidTransform(CoreError)

The checked HOP Core transform evaluator rejected the matrix.

Trait Implementations

impl Clone for ActionError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActionError

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

Formats the value using the given formatter.

impl Display for ActionError

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

Formats the value using the given formatter.

impl Eq for ActionError

impl Error for ActionError

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 ActionError

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

Equality operator ==.

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

Inequality operator !=.
