Enum SpectralError

pub enum SpectralError {
    InvalidParameter(String),
    InvalidSize(String),
    Numerical(String),
    Audio(AudioError),
    TimeDomain(String),
    TimeFrequency(String),
}

Custom error types for spectral signal processing operations.

This enum defines errors specific to spectral feature extraction and analysis.

Variants

InvalidParameter(String)

Error when a parameter (e.g., frame length, hop length) is invalid.

InvalidSize(String)

Error when input dimensions or sizes are insufficient or mismatched.

Numerical(String)

Error during numerical computations (e.g., matrix solving, eigenvalue decomposition).

Audio(AudioError)

Wraps an AudioError from the core module (e.g., from time-domain functions).

TimeDomain(String)

A variant for TimeDomainError

TimeFrequency(String)

Wraps a time-frequency processing error (e.g., from STFT or CQT).

Trait Implementations

impl Debug for SpectralError

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

Formats the value using the given formatter.

impl Display for SpectralError

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

Formats the value using the given formatter.

impl Error for SpectralError

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<AudioError> for SpectralError

fn from(source: AudioError) -> Self

Converts to this type from the input type.
