Failure while compiling symbolic aggregate-rule data for one alphabet.

Variants

Alphabet(AlphabetError)

The alphabet itself was invalid.

ForeignSymbol

A declaration named a symbol outside the alphabet.

Fields

alphabet_id: AlphabetId

Stable alphabet id.

DuplicateDeclaration

The same symbol was declared more than once.

Fields

position: usize

Canonical alphabet position identified from the supplied symbol.

MissingDeclaration

A multiplicity declaration omitted an alphabet symbol.

Fields

position: usize

Canonical alphabet position without a declaration.

ZeroMultiplicity

A multiplicity was zero where the selected rule requires presence.

Fields

position: usize

Canonical alphabet position with zero multiplicity.

NoOmissions

An omission rule named no omitted symbols.

OmitsEverything(AlphabetId)

A rule omitted every symbol and could not admit a musical series.

InvalidProjectionId

Projected class identity did not use the stable portable syntax.

Fields

value: String

Rejected projection id text.

reason: &'static str

Specific syntax violation.

DuplicateProjectionId(ProjectionId)

Two projected classes reused the same stable id.

EmptyProjectionClass(ProjectionId)

A projected class had no source symbols.

DuplicateProjectionMember

An alphabet symbol was assigned to more than one projected class.

Fields

position: usize

Canonical alphabet position assigned twice.

MissingProjectionMember

An alphabet symbol was not assigned to a projected class.

Fields

position: usize

Canonical alphabet position without a class.

MultiplicityOverflow

Declared multiplicities overflowed the platform series length.

AlphabetMismatch

The rule’s declarations were compiled for another alphabet identity.

Fields

rule_id: AlphabetId

Alphabet id retained by the rule.

series_id: AlphabetId

Alphabet id supplied to series construction.

CardinalityMismatch

The rule’s declarations were compiled for another alphabet cardinality.

Fields

expected: usize

Cardinality retained by the rule.

found: usize

Cardinality supplied to series construction.

Trait Implementations

impl Clone for AggregateRuleError

fn clone(&self) -> AggregateRuleError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregateRuleError

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

Formats the value using the given formatter.

impl Display for AggregateRuleError

impl Eq for AggregateRuleError

impl Error for AggregateRuleError

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
