Struct AvError 

pub struct AvError(/* private fields */);

A typed FFmpeg return code.

Wraps the raw negative c_int error code returned by FFmpeg. Display renders it through av_strerror, and is_eagain / is_eof expose the drain states the send/receive loop cares about.

Implementations

impl AvError

pub const fn new(code: c_int) -> Self

Wraps a raw FFmpeg error code.

pub const fn code(self) -> c_int

Returns the raw FFmpeg error code.

pub const fn is_eagain(self) -> bool

Returns true when the code is EAGAIN: the decoder or encoder needs more input before it can produce output.

pub const fn is_eof(self) -> bool

Returns true when the code is AVERROR_EOF: the stream is fully drained and no more output will be produced.

Trait Implementations

impl Clone for AvError

fn clone(&self) -> AvError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for AvError

impl Debug for AvError

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

Formats the value using the given formatter.

impl Eq for AvError

impl Error for AvError

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<i32> for AvError

fn from(code: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for AvError

fn eq(&self, other: &AvError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
