Struct BorrowedObject

pub struct BorrowedObject<'a, T> { /* private fields */ }

Borrowed reference to an object of type T.

This dereferences into &T.

Implementations

impl<'a, T> BorrowedObject<'a, T>

where T: ObjectType,

pub unsafe fn new( ptr: *mut <T as ObjectType>::GlibType, ) -> BorrowedObject<'a, T>

Creates a new borrowed object reference.

SAFETY:

The pointer needs to be valid for at least the lifetime 'a.

pub fn downgrade(&self) -> <BorrowedObject<'a, T> as Downgrade>::Weak

where T: Downgrade,

Downgrade to a weak reference.

Trait Implementations

Formats the value using the given formatter.

impl<T> Deref for BorrowedObject<'_, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T> Downgrade for BorrowedObject<'_, T>

where T: Downgrade + ObjectType,

type Weak = <T as Downgrade>::Weak

Weak reference type.

impl<'a, T> Hash for BorrowedObject<'a, T>

where T: Hash,

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,

impl<'a, T> Ord for BorrowedObject<'a, T>

where T: Ord,

fn cmp(&self, other: &BorrowedObject<'a, T>) -> 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<T> PartialEq<T> for BorrowedObject<'_, T>

where T: PartialEq,

fn eq(&self, other: &T) -> 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<'a, T> PartialEq for BorrowedObject<'a, T>

where T: PartialEq,

fn eq(&self, other: &BorrowedObject<'a, T>) -> 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<T> PartialOrd<T> for BorrowedObject<'_, T>

where T: PartialOrd,

fn partial_cmp(&self, other: &T) -> 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.
