Struct ArcRwSignal 

pub struct ArcRwSignal<T> { /* private fields */ }

Implementations

impl<T> ArcRwSignal<T>

pub fn new(value: T) -> Self

Create a new ArcRwSignal with the given initial value

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

Get a read guard to the data (like Arc<RwLock>::read()) This does NOT subscribe to reactive effects.

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

Get a write guard to the data (like Arc<RwLock>::write()) This will notify reactive effects when the guard is dropped.

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

Try to get a read guard without blocking

pub fn try_write(&self) -> Option<ArcRwSignalWriteGuard<'_, T>>

Try to get a write guard without blocking

impl<T: Clone> ArcRwSignal<T>

pub fn get(&self) -> T

Get a clone of the current value and subscribe to changes in reactive contexts

pub fn get_untracked(&self) -> T

Get a clone of the current value without subscribing to changes

pub fn set(&self, value: T)

Set the value, notifying all reactive subscribers

pub fn update<R>(&self, f: impl FnOnce(&mut T) -> R) -> R

Update the value using a closure, notifying all reactive subscribers

pub fn with<R>(&self, f: impl FnOnce(&T) -> R) -> R

Apply a closure to the current value, subscribing to changes in reactive contexts

pub fn with_untracked<R>(&self, f: impl FnOnce(&T) -> R) -> R

Apply a closure to the current value without subscribing to changes

impl<T> ArcRwSignal<T>

pub fn track(&self)

Subscribe to changes in reactive contexts (like signal.track())

pub fn notify(&self)

Manually notify reactive subscribers of changes

pub fn to_read_signal(&self) -> ReadSignal<()>

Get a regular ReadSignal that updates when this ArcRwSignal changes. The returned signal’s value is always () - it’s just for tracking changes.

pub fn to_write_signal(&self) -> WriteSignal<()>

Get a regular WriteSignal that can trigger updates. Writing to this signal will notify subscribers but won’t change the actual data.
