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.

OutOfMemory

InvalidArgument

NotFound

IOError

PipeError

BadFileDescriptor

NotImplemented

OperationNotPermitted

PermissionDenied

Timeout

EncoderNotFound

EncoderUnavailable

A named encoder could not be opened because the linked FFmpeg build does not provide it — either it was compiled without that encoder (e.g. no --enable-libx264) or the name is not a known encoder at all. Unlike the bare EncoderNotFound errno mapping, this names the encoder so the fix is actionable. name is the encoder the caller requested, or the codec the output format guessed when none was set explicitly.

Fields

name: String

MatchesNoStreams(String)

InvalidLabel(String)

NotContainStream

UnknownFrameFormat

InvalidFileIndexInIntput(usize, String)

UnknownError(i32)

InvalidSink

SeekFunctionMissing

FormatUnsupported(String)

UnknownPixelFormat(String)

UnknownSampleFormat(String)

InvalidOption(String)

A builder option carried an invalid value (e.g. a malformed set_force_key_frames spec, an out-of-range set_io_buffer_size). Setters store values as given and defer validation to open time, so a bad value surfaces here instead of panicking in the setter or forcing a Result into the middle of a builder chain.

AttachmentRead(String, Error)

AttachmentEmpty(String)

AttachmentTooLarge(String, u64, u64)

AttachmentEmptyMimetype(String)

Trait Implementations

impl Debug for OpenOutputError

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

Formats the value using the given formatter.

impl Display for OpenOutputError

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

Formats the value using the given formatter.

impl Error for OpenOutputError

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<OpenOutputError> for Error

fn from(source: OpenOutputError) -> Self

Converts to this type from the input type.

impl From<i32> for OpenOutputError

fn from(err_code: i32) -> Self

Converts to this type from the input type.
