Errors from image decoding and video encoding and decoding.

Variants

InsufficientCapacity

Image dimensions exceed the tensor’s capacity.

Fields

image: (usize, usize)

(width, height) of the decoded image.

tensor: (usize, usize)

(width, height) capacity of the destination tensor.

UnsupportedDtype(DType)

The tensor’s element type is not supported for image decoding.

UnsupportedFormat(PixelFormat)

The requested pixel format is not supported for this image type.

Unsupported(UnsupportedFeature)

The image data is well-formed but uses a feature this decoder does not implement. Callers can pattern-match on the carried UnsupportedFeature to react programmatically (e.g. transcode before retry, surface a precise message, or skip gracefully).

InvalidData(String)

The image data is corrupted, truncated, or not a recognized format.

Io(Error)

I/O error reading image data.

Tensor(Error)

An error from the tensor subsystem.

NoDevice(String)

No device can do what was asked, for example no hardware video encoder.

InvalidConfig(String)

A configuration the codec or the device rejects.

InvalidInput(String)

A source frame that does not match the configuration.

Device

A device operation failed.

Fields

op: String

The operation, for example VIDIOC_QBUF.

source: Error

The operating system error.

Timeout(String)

The device did not finish an operation in time.

PoolExhausted

A video decoder has nowhere to decode to: the caller holds the frames in its output buffers. Dropping decoded frames gives their buffers back; a larger pool lets the caller hold more at once.

Fields

held: usize

Output buffers held by frames the caller has not dropped.

pool: usize

Output buffers in the pool.

Implementations

impl CodecError

pub fn cpu_access_denied(&self) -> Option<&Error>

The CpuAccessDenied refusal this error carries, if any.

Trait Implementations

impl Debug for CodecError

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

Formats the value using the given formatter.

impl Display for CodecError

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

Formats the value using the given formatter.

impl Error for CodecError

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.
