Struct gstreamer::Tracer

#[repr(transparent)]
pub struct Tracer { /* private fields */ }

Tracing modules will subclass Tracer and register through gst_tracer_register(). Modules can attach to various hook-types - see [tracing_register_hook()][crate::tracing_register_hook()]. When invoked they receive hook specific contextual data, which they must not modify.

This is an Abstract Base Class, you cannot instantiate it.

parent

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

Implementations

impl Tracer

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

impl Tracer

pub fn register( plugin: Option<&Plugin>, name: &str, type_: Type ) -> Result<(), BoolError>

Trait Implementations

impl Clone for Tracer

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tracer

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

Formats the value using the given formatter.

impl HasParamSpec for Tracer

type ParamSpec = ParamSpecObject

type SetValue = Tracer

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Tracer

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

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<T: TracerImpl> IsSubclassable<T> for Tracer

fn class_init(class: &mut Class<Self>)

Override the virtual methods of this class for the given subclass and do other class initialization.

fn instance_init(instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for Tracer

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl ParentClassIs for Tracer

type Parent = Object

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

fn eq(&self, other: &OT) -> 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<OT: ObjectType> PartialOrd<OT> for Tracer

fn partial_cmp(&self, other: &OT) -> 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 Tracer

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for Tracer

impl IsA<Object> for Tracer

impl Send for Tracer
