Struct RwLock

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

Provides interior mutability.

It’s tailored for internal use in egui should only be used for short locks (as a guideline, locks should never be held longer than a single frame). In debug builds, when a lock can’t be acquired within 10 seconds, we assume a deadlock and will panic.

This is a thin wrapper around parking_lot::RwLock.

Implementations

impl<T> RwLock<T>

pub fn new(val: T) -> Self

impl<T: ?Sized> RwLock<T>

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

Try to acquire read-access to the lock.

Panics

Will panic in debug builds if the lock can’t be acquired within 10 seconds.

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

Try to acquire write-access to the lock.

Panics

Will panic in debug builds if the lock can’t be acquired within 10 seconds.

Trait Implementations

impl<T: Default + ?Sized> Default for RwLock<T>

fn default() -> RwLock<T>

Returns the “default value” for a type.
