Enum PitchScaleError 

pub enum PitchScaleError {
    PitchClassOutOfScale(u8),
    EmptyScale,
    InvalidScaleInterval(u8),
    InvalidScaleDegree(usize),
}

Error returned when a scale operation fails or a scale cannot be constructed.

Variants

PitchClassOutOfScale(u8)

A pitch class was requested as a scale degree but is not part of the scale.

EmptyScale

A custom scale was built from an empty interval list.

InvalidScaleInterval(u8)

A custom scale interval fell outside the valid 0..12 semitone range.

InvalidScaleDegree(usize)

A one-based scale degree was zero or otherwise unsupported.

impl Eq for PitchScaleError

impl Error for PitchScaleError

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 PitchScaleError

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

Equality operator ==.

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

Inequality operator !=.
