Enum SpectrumAnalyzerError 

pub enum SpectrumAnalyzerError {
    InvalidLengthOfSamples,
    InvalidSamplingRate,
    NaNValuesNotSupported,
    InfinityValuesNotSupported,
    InvalidFrequencyLimit(FrequencyLimitError),
    FrequencyLimitTooNarrow,
    ScalingError(f32, f32),
}

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

Variants

InvalidLengthOfSamples

The amount of samples must be a power of 2, at least 2, and no more than 32768.

InvalidSamplingRate

The sampling rate must not be zero.

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.

FrequencyLimitTooNarrow

The frequency limit is valid in isolation but leaves too few frequency bins for a spectrum.

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.
