MutexGuard

ostd::sync

Struct MutexGuard 

Source 
pub struct MutexGuard<'a, T> { /* private fields */ }
Expand description

A guard that provides exclusive access to the data protected by a Mutex.

Implementations§

Source§

impl<'a, T> MutexGuard<'a, T>

Source

pub closed spec fn value(self) -> T

The value stored in the mutex.

Source

pub open spec fn view(self) -> T

{ self.value() }

The value stored in the mutex. It is an alias of Self::value.

Source

pub closed spec fn rel_mutex(self, mutex: Mutex<T>) -> bool

Source§

impl<T> MutexGuard<'_, T>

Source

pub exec fn drop(self)

VERUS LIMITATION: We implement drop and call it manually because Verus’s support for Drop is incomplete for now.

Source§

impl<'a, T> MutexGuard<'a, T>

Source

pub exec fn get_lock(guard: &MutexGuard<'a, T>) -> ret : &'a Mutex<T>

ensures
guard.rel_mutex(*ret),

Returns the Mutex associated with this guard.

Trait Implementations§

Source§

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

Source§

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

returns
self.view(),
Source§

type Target = T

The resulting type after dereferencing.
Source§

impl<T> DerefMut for MutexGuard<'_, T>

Source§

exec fn deref_mut(&mut self) -> ret : &mut Self::Target

ensures
final(self).view() == *final(ret),
old(self).view() == *ret,

Blanket Implementations§

§

impl<T> DerefSpec for T
where T: Deref,

§

fn deref_spec(&self) -> &<T as Deref>::Target

👎Deprecated: If you can, do not use this module as it adds assumptions about the core of Rust’s deref semantics.
§

fn deref_spec_eq(&self)

👎Deprecated: If you can, do not use this module as it adds assumptions about the core of Rust’s deref semantics.
