Struct glib::object::BorrowedObject

#[repr(transparent)]
pub struct BorrowedObject<'a, T> {
    ptr: NonNull<GObject>,
    phantom: PhantomData<&'a T>,
}

Borrowed reference to an object of type T.

This dereferences into &T.

Fields

ptr: NonNull<GObject>

phantom: PhantomData<&'a T>

Implementations

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

pub unsafe fn new(ptr: *mut T::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) -> <Self as Downgrade>::Weak

where T: Downgrade,

Downgrade to a weak reference.

Trait Implementations

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,

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

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 + PartialOrd,

impl<'a, T: PartialEq> PartialEq<T> for BorrowedObject<'a, T>

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.
