Struct gstreamer_controller::LFOControlSource

pub struct LFOControlSource { /* private fields */ }

LFOControlSource is a gst::ControlSource, that provides several periodic waveforms as control values.

To use LFOControlSource get a new instance by calling new(), bind it to a GParamSpec and set the relevant properties.

All functions are MT-safe.

Properties

amplitude

Specifies the amplitude for the waveform of this LFOControlSource.

Readable | Writeable

frequency

Specifies the frequency that should be used for the waveform of this LFOControlSource. It should be large enough so that the period is longer than one nanosecond.

Readable | Writeable

offset

Specifies the value offset for the waveform of this LFOControlSource.

Readable | Writeable

timeshift

Specifies the timeshift to the right that should be used for the waveform of this LFOControlSource in nanoseconds.

To get a n nanosecond shift to the left use “(GST_SECOND / frequency) - n”.

Readable | Writeable

waveform

Specifies the waveform that should be used for this LFOControlSource.

Object

name

Readable | Writeable | Construct

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

LFOControlSourceExt, gst::prelude::ControlSourceExt, gst::prelude::ObjectExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl LFOControlSource

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

pub fn new() -> LFOControlSource

This returns a new, unbound LFOControlSource.

Returns

a new, unbound LFOControlSource.

Trait Implementations

impl Clone for LFOControlSource

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 LFOControlSource

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

Formats the value using the given formatter.

impl Default for LFOControlSource

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for LFOControlSource

type ParamSpec = ParamSpecObject

type SetValue = LFOControlSource

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for LFOControlSource

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 LFOControlSource

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 LFOControlSource

type Parent = ControlSource

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

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 LFOControlSource

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 LFOControlSource

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for LFOControlSource

impl IsA<ControlSource> for LFOControlSource

impl IsA<Object> for LFOControlSource

impl Send for LFOControlSource
