Error variants produced by the crate’s theory helpers.

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.

Music21Object(String)

Error associated with a generic music21-style object.

Chord(String)

Error associated with chord construction or analysis.

Pitch(String)

Error associated with pitch construction, spelling or conversion.

Microtone(String)

Error associated with microtone construction or conversion.

Accidental(String)

Error associated with accidental parsing or conversion.

ChordTables(String)

Error associated with generated chord-table lookup data.

Interval(String)

Error associated with interval construction or conversion.

StepName(String)

Error associated with step-name parsing or conversion.

PitchClass(String)

Error associated with numeric pitch-class parsing.

PitchClassString(String)

Error associated with pitch-class string parsing.

Ordinal(String)

Error associated with ordinal-name parsing.

Polyrhythm(String)

Error associated with polyrhythm construction or timing.

TuningSystem(String)

Error associated with tuning-system parsing or lookup.

Midi(String)

Error associated with MIDI import or export.

Analysis(String)

Error associated with analysis helpers.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Infallible> for Error

fn from(value: Infallible) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

impl Eq for Error

impl StructuralPartialEq for Error
