Expand description

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.

`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!
