Struct rscontainer::Shared

#[repr(transparent)]
pub struct Shared<S: ?Sized + IShared> { /* fields omitted */ }

A pointer to a shared instance from the service container.

Implementations

impl<S: ?Sized + IShared> Shared<S>

pub fn new(inner: S::Pointer) -> Self

Creates a shared instance from the inner smart pointer.

pub fn into_inner(self) -> S::Pointer

Returns the inner smart pointer of the shared instance.

pub fn inner(&self) -> &S::Pointer

Returns a reference to the inner smart pointer.

pub fn inner_mut(&mut self) -> &mut S::Pointer

Returns a reference to the inner smart pointer.

pub fn is(&self, other: &Self) -> bool

Returns true if two shared instances point to the same instance.

Only compares the pointers, not the contents of the shared instances, and is therefore always cheap.

pub fn access<U, F>(&self, f: F) -> U where
    S::Pointer: IAccess,
    F: FnOnce(Poisoning<&<S::Pointer as IAccess>::Target>) -> U, 

Get access to the shared instance through a closure.

pub fn try_access<U, F>(&self, f: F) -> Option<U> where
    S::Pointer: IAccess,
    F: FnOnce(Poisoning<&<S::Pointer as IAccess>::Target>) -> U, 

Get access to the shared instance through a closure.

pub fn access_mut<U, F>(&self, f: F) -> U where
    S::Pointer: IAccessMut,
    F: FnOnce(Poisoning<&mut <S::Pointer as IAccess>::Target>) -> U, 

Get access to the shared instance through a closure.

pub fn try_access_mut<U, F>(&self, f: F) -> Option<U> where
    S::Pointer: IAccessMut,
    F: FnOnce(Poisoning<&mut <S::Pointer as IAccess>::Target>) -> U, 

Get access to the shared instance through a closure.

Trait Implementations

impl<S: ?Sized + IShared> Clone for Shared<S>

fn clone(&self) -> Self

Clones the pointer to the shared instance.

Only increases the reference count, so this is very cheap. See Rc::clone and Arc::clone.

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

Performs copy-assignment from source.

impl<S: ?Sized + IShared> Debug for Shared<S> where
    S::Pointer: Debug, 

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

Formats the value using the given formatter.

impl<S: ?Sized + IShared> Deref for Shared<S> where
    S::Pointer: Deref, 

type Target = <S::Pointer as Deref>::Target

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
