Enum gstreamer::PadMode

#[repr(i32)]
pub enum PadMode {
    None = 0,
    Push = 1,
    Pull = 2,
}

The status of a GstPad. After activating a pad, which usually happens when the parent element goes from READY to PAUSED, the GstPadMode defines if the pad operates in push or pull mode.

Variants

None = 0

Pad will not handle dataflow

Push = 1

Pad handles dataflow in downstream push mode

Pull = 2

Pad handles dataflow in upstream pull mode

Implementations

impl PadMode

pub fn name<'a>(self) -> &'a GStr

Trait Implementations

impl Clone for PadMode

fn clone(&self) -> PadMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PadMode

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

Formats the value using the given formatter.

impl Display for PadMode

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

Formats the value using the given formatter.

impl From<PadMode> for Value

fn from(v: PadMode) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for PadMode

type Checker = GenericValueTypeChecker<PadMode>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for PadMode

type ParamSpec = ParamSpecEnum

type SetValue = PadMode

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for PadMode

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 PadMode

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

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

impl PartialOrd for PadMode

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

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

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

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

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

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.

impl StaticType for PadMode

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for PadMode

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 PadMode

type Type = PadMode

Type to get the Type from.

impl Copy for PadMode

impl Eq for PadMode
