Stream errors are for anything related to the stream being processed: format errors, media type errors, … They’re typically used by decoders, demuxers, converters, …

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.

Failed

a general error which doesn’t fit in any other category. Make sure you add a custom message to the error call.

TooLazy

do not use this except as a placeholder for deciding where to go while developing code.

NotImplemented

use this when you do not want to implement this functionality yet.

TypeNotFound

used when the element doesn’t know the stream’s type.

WrongType

used when the element doesn’t handle this type of stream.

CodecNotFound

used when there’s no codec to handle the stream’s type.

Decode

used when decoding fails.

Encode

used when encoding fails.

Demux

used when demuxing fails.

Mux

used when muxing fails.

Format

used when the stream is of the wrong format (for example, wrong caps).

Decrypt

used when the stream is encrypted and can’t be decrypted because this is not supported by the element.

DecryptNokey

used when the stream is encrypted and can’t be decrypted because no suitable key is available.

Trait Implementations

impl Clone for StreamError

fn clone(&self) -> StreamError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StreamError

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

Formats the value using the given formatter.

impl ErrorDomain for StreamError

fn domain() -> Quark

Returns the quark identifying the error domain.

fn code(self) -> i32

Gets the integer representation of the variant.

fn from(code: i32) -> Option<Self>

Tries to convert an integer code to an enum variant.

impl From<StreamError> for Value

fn from(v: StreamError) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for StreamError

type Checker = GenericValueTypeChecker<StreamError>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for StreamError

type ParamSpec = ParamSpecEnum

type SetValue = StreamError

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: StreamError) -> ParamSpecEnumBuilder<'_, StreamError>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for StreamError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for StreamError

fn cmp(&self, other: &StreamError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for StreamError

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

This method tests for self and other values to be equal, and is used by ==.

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

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for StreamError

type Type = StreamError

Type to get the Type from.

impl Copy for StreamError
