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.

NoEncoder(String)

No encoder matching the requested codec / hardware preference could be opened (none compiled in, or none available on this machine).

NoDecoder(String)

No decoder matching the requested codec / hardware preference could be opened (none compiled in, or none available on this machine).

UnknownEncoder

Kind::Named asked for an encoder this build does not have for that codec: a name that is not a backend, one whose feature is off, or one that does not encode the codec requested.

Fields

name: String

The name that was asked for.

codec: Codec

The codec it was asked for.

available: String

The encoders this build does have for that codec.

UnknownDecoder

Kind::Named asked for a decoder this build does not have for that codec: a name that is not a backend, one whose feature is off, or one that does not decode the codec requested.

Fields

name: String

The name that was asked for.

codec: Codec

The codec it was asked for.

available: String

The decoders this build does have for that codec.

UnsupportedCodec(String)

A track’s codec is not supported by the native decoders.

CodecGone(String)

The codec session is over: its worker thread stopped, or a cancelled call left it out of step with the stream it was decoding.

Distinct from Codec, which describes the bytes of one picture and which a caller can reasonably skip past. Nothing about this one improves by reading on: the session that would have decoded the next picture no longer exists, and only a new encoder or decoder recovers it.

Unsupported(String)

The requested capture source or enumeration has no implementation on this platform (the message names what is missing).

PermissionDenied(String)

The operating system denied access to a capture source.

SourceUnavailable(String)

A requested capture source does not exist or disappeared while capturing.

InvalidFramerate(u32)

The configured framerate is outside the supported range.

BitrateUnsupported(&'static str)

This encoder can’t change its bitrate once open, so it can’t follow a congestion-control estimate. Encoding continues at the configured rate.

Render(Error)

GPU rendering failure: building the pipeline, importing a frame’s surface as a texture, or the device itself.

Codec(Error)

Capture / encode / codec failure (the message carries the detail).

Mux(Error)

moq-mux muxer/catalog error.

Net(Error)

moq-net transport error.

TimeOverflow(TimeOverflow)

Timestamp overflow converting to the moq microsecond timescale.

Trait Implementations

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, __formatter: &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
