Enum MfccError 

pub enum MfccError {
    InvalidDimensions(String),
    InvalidInput(String),
    ComputationFailed(String),
}

Error conditions for MFCC processing and reconstruction.

Enumerates specific failure modes in MFCC delta computation and spectrogram/audio reconstruction, tailored for DSP pipeline diagnostics.

Variants

InvalidDimensions(String)

Input dimensions are invalid (e.g., empty matrix).

InvalidInput(String)

Input parameters are invalid (e.g., negative width, even width).

ComputationFailed(String)

Numerical computation failure (e.g., overflow in reconstruction).

Trait Implementations

impl Debug for MfccError

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

Formats the value using the given formatter.

impl Display for MfccError

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

Formats the value using the given formatter.

impl Error for MfccError

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.
