Something wrong with a frame-export request or run.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoVideoStream

The input has no video stream to export from.

StreamIndexOutOfBounds

An explicit video_stream_index was out of range.

Fields

index: usize

The requested (out-of-range) index.

count: usize

The number of streams the input actually has.

NotAVideoStream

An explicit video_stream_index referred to a non-video stream.

Fields

index: usize

The requested index.

UnknownDuration

UniformN needs a duration, and none could be resolved.

HdrRequiresToneMapping

The input is HDR (BT.2020 / PQ / HLG). Tone mapping is a documented non-goal of this module.

EmptyVideoStream

UniformN(n) was requested but the video stream produced no frames.

Fields

n: u32

The requested exact frame count.

InvalidOption(String)

An option value was invalid (zero count, zero size, non-finite seconds, …).

NoAudioStream

The input has no audio stream to export from.

AudioStreamIndexOutOfBounds

An explicit audio_stream_index was out of range.

Fields

index: usize

The requested (out-of-range) index.

count: usize

The number of streams the input actually has.

NotAnAudioStream

An explicit audio_stream_index referred to a non-audio stream.

Fields

index: usize

The requested index.

Trait Implementations

impl Debug for FrameExportError

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

Formats the value using the given formatter.

impl Display for FrameExportError

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

Formats the value using the given formatter.

impl Error for FrameExportError

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<FrameExportError> for Error

fn from(source: FrameExportError) -> Self

Converts to this type from the input type.
