Struct MutRefGuard 

pub struct MutRefGuard<'a, V> { /* private fields */ }

Mutable guard without value lock, only structure lock (mutable access) 无值锁的可变守护者，只有结构锁（可变访问）

Safety

此结构绕过了保护值的 RwLock，仅当您确定没有其他线程正在修改该值时才应使用。 This struct bypasses the RwLock protecting the value. It should only be used when you are sure that no other thread is modifying the value.

Trait Implementations

impl<'a, V> AsMut<V> for MutRefGuard<'a, V>

fn as_mut(&mut self) -> &mut V

Converts this type into a mutable reference of the (usually inferred) input type.

impl<'a, V> AsRef<V> for MutRefGuard<'a, V>

fn as_ref(&self) -> &V

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a, V> Debug for MutRefGuard<'a, V>

where V: Debug,

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

Formats the value using the given formatter.

impl<'a, V> Deref for MutRefGuard<'a, V>

type Target = V

The resulting type after dereferencing.

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

Dereferences the value.

impl<'a, V> DerefMut for MutRefGuard<'a, V>

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

Mutably dereferences the value.

impl<'a, V> Display for MutRefGuard<'a, V>

where V: Display,

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

Formats the value using the given formatter.

impl<'a, V> PartialEq for MutRefGuard<'a, V>

where V: PartialEq,

fn eq(&self, other: &Self) -> 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.

impl<'a, V> Eq for MutRefGuard<'a, V>

where V: Eq,
