Struct Read Only RwLock &nbsp; Copy item path

impl<T> ReadOnlyRwLock<T>

pub fn new(l: Arc<RwLock<RawRwLock, T>>) -> ReadOnlyRwLock<T>

New.

pub fn read(&self) -> RwLockReadGuard<'_, RawRwLock, T>

Locks this RwLock with shared read access, blocking the current thread until it can be acquired.

See parking_lot::RwLock::read for more details.

pub fn read_recursive(&self) -> RwLockReadGuard<'_, RawRwLock, T>

Locks this RwLock with shared read access, blocking the current thread until it can be acquired.

Unlike read, this method is guaranteed to succeed without blocking if another read lock is held at the time of the call.

See parking_lot::RwLock::read_recursive for more details.

pub fn try_read(&self) -> Option<RwLockReadGuard<'_, RawRwLock, T>>

Attempts to acquire this RwLock with shared read access.

See parking_lot::RwLock::try_read for more details.

pub fn try_read_recursive(&self) -> Option<RwLockReadGuard<'_, RawRwLock, T>>

Attempts to acquire this RwLock with shared read access.

See parking_lot::RwLock::try_read_recursive for more details.

pub fn ptr_eq(&self, other: &ReadOnlyRwLock<T>) -> bool

Gets if the read-only shared reference is to the same lock as other.

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> CloneToUninit for T
where T: Clone,

unsafe fn clone_to_uninit(&self, dest: *mut u8)

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

Performs copy-assignment from self to dest. Read more

impl<T> Downcast for T
where T: Any,

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.

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.

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.

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> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

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

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T> Instrument for T

fn instrument(self, span: Span) -> Instrumented<Self>

impl<T> Instrument for T

fn instrument(self, span: Span) -> Instrumented<Self>

fn into_either_with<F>(self, into_left: F) -> Either<Self, Self>
where F: FnOnce(&Self) -> bool,

Converts self into a Left variant of Either<Self, Self> if into_left(&self) returns true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more
