Enum Error

#[non_exhaustive]
pub enum Error {
    Again,
    InvalidArgument,
    NotEnoughMemory,
    UnsupportedBitstream,
    UnknownError(i32),
}

Error enum return by various dav1d operations.

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.

Again

Try again.

If this is returned by Decoder::send_data or Decoder::send_pending_data then there are decoded frames pending that first have to be retrieved via Decoder::get_picture before processing any further pending data.

If this is returned by Decoder::get_picture then no decoded frames are pending currently and more data needs to be sent to the decoder.

InvalidArgument

Invalid argument.

One of the arguments passed to the function was invalid.

NotEnoughMemory

Not enough memory.

Not enough memory is currently available for performing this operation.

UnsupportedBitstream

Unsupported bitstream.

The provided bitstream is not supported by dav1d.

UnknownError(i32)

Unknown error.

Implementations

impl Error

pub const fn is_again(&self) -> bool

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(err: i32) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
