Struct ReentrantLockGuard

Source

pub struct ReentrantLockGuard<'a, T>where
    T: 'a + ?Sized,
{ /* private fields */ }

🔬This is a nightly-only experimental API. (reentrant_lock)

Expand description

An RAII implementation of a “scoped lock” of a re-entrant lock. When this structure is dropped (falls out of scope), the lock will be unlocked.

The data protected by the mutex can be accessed through this guard via its Deref implementation.

This structure is created by the lock method on ReentrantLock.

§Mutability

Unlike MutexGuard, ReentrantLockGuard does not implement DerefMut, because implementation of the trait would violate Rust’s reference aliasing rules. Use interior mutability (usually RefCell) in order to mutate the guarded data.

Blanket Implementations§

Source §

impl<T> Any for T

Source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl As for U

Source §

fn as_<T>(self) -> T
where T: CastFrom,

Casts self to type T. The semantics of numeric casting with the as operator are followed, so <T as As>::as_:: can be used in the same way as T as U for numeric conversions. Read more

Source §

impl<T> Borrow<T> for T
where T: ?Sized,

Source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Source §

impl<T> BorrowMut<T> for T
where T: ?Sized,

Source §

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> From<T> for T

Source §

fn from(t: T) -> T

Returns the argument unchanged.

Source §

impl<T> FromBits<T> for T

Source §

fn from_bits(other: T) -> T

Convert other to Self, preserving bitwise representation

Source §

impl<T, U> Into for T
where U: From<T>,

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
