#[repr(transparent)]
pub struct Promise {
    inner: Shared<GstPromise, Self>,

Implementations

impl Promise

pub fn as_ptr(&self) -> *mut GstPromise

pub unsafe fn from_glib_ptr_borrow(ptr: &*mut GstPromise) -> &Self

Borrows the underlying C value.

impl Promise

pub fn new() -> Promise

pub fn with_change_func<F>(func: F) -> Promise

where F: FnOnce(Result<Option<&StructureRef>, PromiseError>) + Send + 'static,

pub fn new_future() -> (Self, PromiseFuture)

pub fn expire(&self)

pub fn get_reply(&self) -> Option<&StructureRef>

pub fn interrupt(&self)

pub fn reply(&self, s: Option<Structure>)

pub fn wait(&self) -> PromiseResult

Trait Implementations

impl Clone for Promise

fn clone(&self) -> Self

Makes a clone of this shared reference.

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

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

Performs copy-assignment from source.

impl Debug for Promise

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

Formats the value using the given formatter.

impl Default for Promise

fn default() -> Self

Returns the “default value” for a type.

impl From<Promise> for Value

fn from(s: Promise) -> Self

Converts to this type from the input type.

impl HasParamSpec for Promise

type ParamSpec = ParamSpecBoxed

type SetValue = Promise

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

type BuilderFn = fn(_: &str) -> ParamSpecBoxedBuilder<'_, Promise>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Promise

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 Promise

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

Restrict a value to a certain interval.

impl PartialEq for Promise

fn eq(&self, other: &Promise) -> 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 Promise

fn partial_cmp(&self, other: &Promise) -> 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 StaticType for Promise

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for Promise

impl Send for Promise

impl StructuralPartialEq for Promise

impl Sync for Promise
