Struct reffers::rc::Strong

pub struct Strong<T: ?Sized + Repr, M: BitMask = u32>(_, _);

A strong reference without access to the inner value.

To get immutable/mutable access, you need to use the get_ref/get_refmut functions to create Ref or RefMut references.

The inner value cannot be dropped while Strong, Ref or RefMut references exist.

pub fn get_mut(&self) -> RefMut<T, M>

Deprecated:

Returns a new RefMut, or panics if this is not possible

Will panic in case a RefMut or Ref is currently held

pub fn try_get_mut(&self) -> Result<RefMut<T, M>, State>

Deprecated:

Renamed to try_get_refmut

Returns a new RefMut, or panics if this is not possible

Will return an error in case a RefMut or Ref is currently held

pub fn get_refmut(&self) -> RefMut<T, M>

Returns a new RefMut, or panics if this is not possible

Will panic in case a RefMut or Ref is currently held

pub fn try_get_refmut(&self) -> Result<RefMut<T, M>, State>

Returns a new RefMut, or panics if this is not possible

Will return an error in case a RefMut or Ref is currently held

pub fn get_ref(&self) -> Ref<T, M>

Returns a new Ref, or panics if this is not possible

Will panic in case a RefMut is currently held, or there are no more Refs available

pub fn try_get_ref(&self) -> Result<Ref<T, M>, State>

Returns a new Ref, or returns an error if there are no such references available

Will return an error in case a RefMut is currently held, or there are no more Refs available

pub fn get(&self) -> Ref<T, M>

Deprecated:

Renamed to get_ref

Returns a new Ref, or panics if this is not possible

Will panic in case a RefMut is currently held, or there are no more Refs available

pub fn try_get(&self) -> Result<Ref<T, M>, State>

Deprecated:

Renamed to try_get_ref

Returns a new Ref, or returns an error if there are no such references available

Will return an error in case a RefMut is currently held, or there are no more Refs available

pub fn get_weak(&self) -> Weak<T, M>

Returns a new Weak reference, or panics if there are no such references available

pub fn get_strong(&self) -> Strong<T, M>

Returns a new Strong reference, or panics if there are no such references available

pub fn try_get_weak(&self) -> Result<Weak<T, M>, State>

Returns a new Weak reference, or returns an error if there are no such references available

pub fn try_get_strong(&self) -> Result<Strong<T, M>, State>

Returns a new Strong reference, or returns an error if there are no such references available

pub fn state(&self) -> State

Returns the current state

pub fn unpoison(&self) -> Result<(), State>

Reverts poisoning

Poisoning happens when a RefMut is dropped during a panic.
