Enum gstreamer::State

#[repr(i32)]
pub enum State {
    VoidPending = 0,
    Null = 1,
    Ready = 2,
    Paused = 3,
    Playing = 4,
}

The possible states an element can be in. States can be changed using ElementExt::set_state() and checked using ElementExt::state().

Variants

VoidPending = 0

no pending state.

Null = 1

the NULL state or initial state of an element.

Ready = 2

the element is ready to go to PAUSED.

Paused = 3

the element is PAUSED, it is ready to accept and process data. Sink elements however only accept one buffer and then block.

Playing = 4

the element is PLAYING, the Clock is running and the data is flowing.

Implementations

impl State

pub fn next(self, pending: Self) -> Self

Trait Implementations

impl Clone for State

Returns a copy of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for State

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<State> for Value

fn from(v: State) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for State

type Checker = GenericValueTypeChecker<State>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for State

type ParamSpec = ParamSpecEnum

type SetValue = State

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for State

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 State

fn cmp(&self, other: &State) -> 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 State

fn eq(&self, other: &State) -> 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.

impl PartialOrd for State

fn partial_cmp(&self, other: &State) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for State

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StaticType for State

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for State

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for State

type Type = State

Type to get the Type from.
