Opus parsing errors.

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.

HeadTooShort

The OpusHead packet was shorter than the 19-byte minimum (RFC 7845 §5.1).

InvalidSignature

The packet did not start with the OpusHead magic signature.

UnsupportedVersion(u8)

The OpusHead major version (the upper four bits) is not one this parser understands, so none of its fields can be trusted (RFC 7845 §5.1).

UnsupportedChannelCount(u32)

The channel count is zero, or more than the channel mapping family allows: family 0 covers mono/stereo and family 1 up to eight channels.

MappingTableTooShort

A nonzero channel mapping family without its complete mapping table.

InvalidMappingTable

The channel mapping table names no streams, more coupled streams than streams, or a channel index past the decoded streams.

UnsupportedMappingFamily(u8)

A channel mapping family the operation cannot carry: family 0 given to Mapping::new, which has no table; a Config::encode whose mapping_family is not its mapping’s; or a container with no room for the table.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate 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, __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

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
