Struct gstreamer_controller::InterpolationControlSource

pub struct InterpolationControlSource { /* private fields */ }

InterpolationControlSource is a gst::ControlSource, that interpolates values between user-given control points. It supports several interpolation modes and property types.

To use InterpolationControlSource get a new instance by calling new(), bind it to a GParamSpec and set some control points by calling TimedValueControlSourceExt::set().

All functions are MT-safe.

parent

The parent of the object. Please note, that when changing the ‘parent’ property, we don’t emit GObject::notify and deep-notify signals due to locking issues. In some cases one can use GstBin::element-added or GstBin::element-removed signals on the parent to achieve a similar effect.

Implements

InterpolationControlSourceExt, TimedValueControlSourceExt, gst::prelude::ControlSourceExt, gst::prelude::ObjectExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl InterpolationControlSource

pub const NONE: Option<&'static InterpolationControlSource> = None

pub fn new() -> InterpolationControlSource

This returns a new, unbound InterpolationControlSource.

Returns

a new, unbound InterpolationControlSource.

Trait Implementations

impl Clone for InterpolationControlSource

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for InterpolationControlSource

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

Formats the value using the given formatter.

impl Default for InterpolationControlSource

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for InterpolationControlSource

type ParamSpec = ParamSpecObject

type SetValue = InterpolationControlSource

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

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, InterpolationControlSource>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for InterpolationControlSource

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

where H: Hasher,

Hashes the memory address of this object.

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 InterpolationControlSource

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

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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 ParentClassIs for InterpolationControlSource

type Parent = TimedValueControlSource

impl<OT: ObjectType> PartialEq<OT> for InterpolationControlSource

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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<OT: ObjectType> PartialOrd<OT> for InterpolationControlSource

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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 InterpolationControlSource

fn static_type() -> Type

Returns the type identifier of Self.
