Struct ReadGuard

pub struct ReadGuard<'a, T: Sized + Sync + 'a> { /* private fields */ }

Expand description

A read-guard that can be used to read the underlying data structure. Writes on the data structure will be blocked as long as one of these is lying around.

Trait Implementations§

impl<T: Sized + Sync> Deref for ReadGuard<'_, T>

This Deref trait allows a thread to use T from a ReadGuard. ReadGuard can only be dereferenced into an immutable reference.

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: Sized + Sync> Drop for ReadGuard<'_, T>

This Drop trait implements the unlock logic for a reader lock. Once the ReadGuard goes out of scope, the corresponding read lock is marked as released.

fn drop(&mut self)

Executes the destructor for this type. Read more

impl<'a, T> Send for ReadGuard<'a, T>

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

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

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

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

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

Mutably borrows from an owned value. Read more

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T, U> Into<U> 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.

impl<P, T> Receiver for P
where P: Deref<Target = T> + ?Sized, T: ?Sized,

type Target = T

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

The target type on which the method may be called.

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

type Error = Infallible

The type returned in the event of a conversion error.

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.
