Typed refusal of the fixed-configuration staging contract.

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.

ConfigurationUnavailable

Encoder cannot declare its container configuration before input.

VideoConfigurationRequired

Configuration does not describe video.

OfferMismatch

Conversion’s bounded facts disagree with its full target.

ConversionMismatch

Conversion returned different interpretation or timing.

ReceivePendingWithoutPacket

Encoder promised pending output but did not return a packet.

EarlyEnd

Encoder ended before the caller finished input.

ConfigurationChanged

Encoder changed the configuration or fidelity bound at preparation.

InputAfterEnd

Encoder requested input after end_input.

EmptyPacket

Encoder returned an empty or taken packet.

Terminal

Operation previously failed or unwound.

NoAdmittedFrames

No input frame completed policy admission. Empty output is unsupported.

PolicyChangedAfterInput

The legacy preset setter was called after input had been accepted.

Trait Implementations

impl Clone for Refusal

fn clone(&self) -> Refusal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Refusal

impl Debug for Refusal

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

Formats the value using the given formatter.

impl Eq for Refusal

impl Error for Refusal

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 PartialEq for Refusal

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

Equality operator ==.

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

Inequality operator !=.
