Struct netstack3_core::sync::RwLock

pub struct RwLock<T>(/* private fields */);

A sync::RwLock assuming lock poisoning will never occur.

Implementations

impl<T> RwLock<T>

pub fn new(t: T) -> RwLock<T>

Creates a new instance of an RwLock<T> which is unlocked.

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

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

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

Panics

This method may panic if the calling thread already holds the read or write lock.

pub fn write(&self) -> LockGuard<'_, RwLock<T>, RwLockWriteGuard<'_, T>>

Locks this rwlock with exclusive write access, blocking the current thread until it can be acquired.

See sync::RwLock::write for more details.

Panics

This method may panic if the calling thread already holds the read or write lock.

pub fn into_inner(self) -> T

Consumes this rwlock, returning the underlying data.

pub fn get_mut(&mut self) -> &mut T

Returns a mutable reference to the underlying data.

Since this call borrows the RwLock mutably, no actual locking needs to take place. See sync::RwLock::get_mut for more details.

Trait Implementations

impl<T> Debug for RwLock<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for RwLock<T>

where T: Default,

fn default() -> RwLock<T>

Returns the “default value” for a type.

impl<T, I> GenericOverIp<I> for RwLock<T>

where I: Ip, T: GenericOverIp<I>,

type Type = RwLock<<T as GenericOverIp<I>>::Type>

impl<T> ReadWriteLock<T> for RwLock<T>

where T: 'static,

type ReadGuard<'l> = LockGuard<'l, RwLock<T>, RwLockReadGuard<'l, T>>

The guard type returned when locking for reads (i.e. shared).

type WriteGuard<'l> = LockGuard<'l, RwLock<T>, RwLockWriteGuard<'l, T>>

The guard type returned when locking for writes (i.e. exclusive).

fn read_lock(&self) -> <RwLock<T> as ReadWriteLock<T>>::ReadGuard<'_>

Locks this lock for reading.

fn write_lock(&self) -> <RwLock<T> as ReadWriteLock<T>>::WriteGuard<'_>

Locks this lock for writing.
