impl ObjectManager

pub fn add_interest<I: Into<ObjectInterest>>(&self, interest: I)

pub fn objects<T: ObjectType>(&self) -> IntoValueIterator<T>

pub fn filtered<T: ObjectType>( &self, interest: ObjectInterest ) -> IntoValueIterator<T>

pub fn lookup<T: ObjectType>(&self, interest: Interest<T>) -> Option<T>

pub fn installed_future(&self) -> impl Future<Output = Result<(), Error>>

Available on crate feature futures only.

Wait until the ObjectManager has been installed.

Note that the future does not take ownership over self, and will produce an error in cases where there are no more references keeping it alive.

Trait Implementations

impl Clone for ObjectManager

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 ObjectManager

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

Formats the value using the given formatter.

impl Default for ObjectManager

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for ObjectManager

type ParamSpec = ParamSpecObject

type SetValue = ObjectManager

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ObjectManager

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<T: ObjectType> InterestContainer<T> for ObjectManager

fn filter(&self, interest: Interest<T>) -> IntoValueIterator<T>

fn lookup(&self, interest: Interest<T>) -> Option<T>

impl<'a> IntoIterator for &'a ObjectManager

type Item = Object

The type of the elements being iterated over.

type IntoIter = ValueIterator<Object>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Ord for ObjectManager

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 ObjectManager

type Parent = Object

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

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 ObjectManager

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 ObjectManager

fn static_type() -> Type

Returns the type identifier of Self.
