Enum FftBackendError 

pub enum FftBackendError {
    NoAdapter,
    DeviceCreation(String),
    ShaderCompilation(String),
    Buffer(String),
    NonPowerOfTwo(usize),
}

Errors specific to the wgpu FFT back-end.

Variants

NoAdapter

No compatible GPU adapter was found on this system.

DeviceCreation(String)

The adapter was found but the device could not be created.

ShaderCompilation(String)

A shader compilation error occurred.

Buffer(String)

A buffer operation (upload/readback) failed.

NonPowerOfTwo(usize)

The input length is not a power of two (required by the shader).

Trait Implementations

impl Debug for FftBackendError

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

Formats the value using the given formatter.

impl Display for FftBackendError

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

Formats the value using the given formatter.

impl Error for FftBackendError

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.

impl From<FftBackendError> for FFTError

fn from(e: FftBackendError) -> Self

Converts to this type from the input type.
