Enum SpectrumAnalyzerError

pub enum SpectrumAnalyzerError {
    TooFewSamples,
    NaNValuesNotSupported,
    InfinityValuesNotSupported,
    InvalidFrequencyLimit(FrequencyLimitError),
    SamplesLengthNotAPowerOfTwo,
    ScalingError(f32, f32),
}

Describes main errors of the library. Almost all errors are caused by wrong input.

Variants

TooFewSamples

There must be at least two samples.

NaNValuesNotSupported

NaN values in samples are not supported!

InfinityValuesNotSupported

Infinity-values (regarding floating point representation) in samples are not supported!

InvalidFrequencyLimit(FrequencyLimitError)

The frequency is invalid. See FrequencyLimitError.

SamplesLengthNotAPowerOfTwo

The number of samples must be a power of two in order for the FFT.

ScalingError(f32, f32)

After applying the scaling function on a specific item, the returned value is either infinity or NaN, according to IEEE-754. This is invalid. Check your scaling function!

Trait Implementations

impl Debug for SpectrumAnalyzerError

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

Formats the value using the given formatter.

impl Display for SpectrumAnalyzerError

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

Formats the value using the given formatter.

impl Error for SpectrumAnalyzerError

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.
