Enum spectrum_analyzer::error::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)

See crate::limit::FrequencyLimitError.

Tuple Fields of InvalidFrequencyLimit

0: FrequencyLimitError

SamplesLengthNotAPowerOfTwo

The number of samples must be a power of two in order for the FFT to be fast and, depending on the used FFT implementation, to work at all.

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!
