Enum realfft::FftError

pub enum FftError {
    InputBuffer(usize, usize),
    OutputBuffer(usize, usize),
    ScratchBuffer(usize, usize),
    InputValues(bool, bool),
}

Custom error returned by FFTs

Variants

InputBuffer(usize, usize)

The input buffer has the wrong size. The transform was not performed.

The first member of the tuple is the expected size and the second member is the received size.

OutputBuffer(usize, usize)

The output buffer has the wrong size. The transform was not performed.

The first member of the tuple is the expected size and the second member is the received size.

ScratchBuffer(usize, usize)

The scratch buffer has the wrong size. The transform was not performed.

The first member of the tuple is the minimum size and the second member is the received size.

InputValues(bool, bool)

The input data contained a non-zero imaginary part where there should have been a zero. The transform was performed, but the result may not be correct.

The first member of the tuple represents the first index of the complex buffer and the second member represents the last index of the complex buffer. The values are set to true if the corresponding complex value contains a non-zero imaginary part.

Trait Implementations

impl Debug for FftError

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

Formats the value using the given formatter.

impl Display for FftError

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

Formats the value using the given formatter.

impl Error for FftError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)
