Errors produced by validate.

Variants

ConfidenceExceedsSourceBound

A confidence value exceeded the bound for its source kind.

Fields

requested: Confidence

The requested confidence.

bound: Confidence

The source kind’s bound.

source_kind: SourceKind

The source kind derived from the source symbol.

SourceKindNotAdmitted

The source kind does not admit the memory kind.

Fields

source_kind: SourceKind

The derived source kind.

memory_kind: MemoryKindTag

The memory kind being written.

FutureValidity

Agent supplied a future valid_at without the :projected true flag.

Fields

valid_at: ClockTime

The offending timestamp.

InvalidClockOrder

Episodic observed_at predates at_time.

Fields

at_time: ClockTime

The event time.

observed_at: ClockTime

The observation time.

EmptyDerivedFrom

Inferential derived_from is empty.

MissingKeyword

A required keyword was missing post-bind. (Normally caught in parse, but present here as a safety net for future form changes.)

Fields

keyword: &'static str

Missing keyword.

form: &'static str

Form being validated.

BadKeywordType

A keyword had the wrong type for the semantic stage.

Fields

keyword: &'static str

Keyword.

form: &'static str

Form.

expected: &'static str

Description of expected type.

ConfidenceMalformed(ConfidenceError)

A confidence value was malformed (e.g. NaN).

CorrectsNonEpisodic

A correct form’s corrected body is not an Epi form.

MultipleEpisodeDirectives

A batch contains more than one (episode …) directive. Per episode-semantics.md § 3 / § 11, each batch corresponds to at most one Episode, so a single directive per batch is the only coherent shape.

Fields

count: usize

Number of episode forms in the batch.

Trait Implementations

impl Debug for SemanticError

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

Formats the value using the given formatter.

impl Display for SemanticError

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

Formats the value using the given formatter.

impl Error for SemanticError

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 From<ConfidenceError> for SemanticError

fn from(source: ConfidenceError) -> Self

Converts to this type from the input type.

impl From<SemanticError> for PipelineError

fn from(source: SemanticError) -> Self

Converts to this type from the input type.

impl PartialEq for SemanticError

fn eq(&self, other: &SemanticError) -> 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.
