Enum AllocOutputContextError 

#[non_exhaustive]
pub enum AllocOutputContextError {
    OutOfMemory,
    InvalidArgument,
    NotFound,
    IOError,

}

Errors from allocating an output format context (avformat_alloc_output_context2).

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

Memory allocation failed (AVERROR(ENOMEM)).

InvalidArgument

FFmpeg rejected an argument as invalid (AVERROR(EINVAL)).

NotFound

The file or stream does not exist (AVERROR(ENOENT)).

IOError

A low-level I/O error occurred (AVERROR(EIO)).

PipeError

The stream or data connection was broken (AVERROR(EPIPE)).

BadFileDescriptor

An invalid file descriptor was used (AVERROR(EBADF)).

NotImplemented

The functionality or output format is not supported by the linked FFmpeg build (AVERROR(ENOSYS)).

OperationNotPermitted

The operation was not permitted (AVERROR(EPERM)).

PermissionDenied

Permission was denied (AVERROR(EACCES)).

Timeout

The operation timed out (AVERROR(ETIMEDOUT)).

UnknownError(i32)

Any other failure; the payload is the raw FFmpeg error code (rendered with av_err2str in the message).

Trait Implementations

impl Debug for AllocOutputContextError

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

Formats the value using the given formatter.

impl Display for AllocOutputContextError

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

Formats the value using the given formatter.

impl Error for AllocOutputContextError

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<AllocOutputContextError> for Error

fn from(source: AllocOutputContextError) -> Self

Converts to this type from the input type.

impl From<i32> for AllocOutputContextError

fn from(err_code: i32) -> Self

Converts to this type from the input type.
