Variants

ImageLengthMismatch

A map image length did not match its octave-space domain.

Fields

domain_len: usize

Domain length.

image_len: usize

Image length.

DomainMismatch

Two composed maps used different octave spaces.

Fields

left_len: u16

Left map domain length.

right_len: u16

Right map domain length.

NoMappedEntries

A map with a nudge policy had no mapped entries to nudge toward.

Unmapped

A reject policy encountered an unmapped source class.

Fields

class: u16

Folded source class.

UnsupportedPitchDomain

The map can be composed as an integer map but cannot be applied to octave-aware Pitch values.

Fields

divisions: u16

Domain division count.

TargetOutOfRange

A mapped absolute value cannot be represented as a Pitch semitone.

Fields

value: i64

Absolute target value.

Trait Implementations

impl Clone for MapError

fn clone(&self) -> MapError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MapError

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

Formats the value using the given formatter.

impl Display for MapError

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

Formats the value using the given formatter.

impl Eq for MapError

impl Error for MapError

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 MapError

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

Equality operator ==.

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

Inequality operator !=.
