Struct SignalCell 

pub struct SignalCell<T>
where
    T: Clone + PartialEq + 'static,
{ /* private fields */ }

A Sync wrapper for single-threaded global Signal access.

SAFETY: This type is only safe to use in single-threaded contexts (e.g., WASM). It implements Sync to allow usage as a static variable, but concurrent access from multiple threads would be undefined behavior.

Implementations

impl<T> SignalCell<T>

where T: Clone + PartialEq + 'static,

Implementation of SignalCell construction and access.

pub const fn empty() -> Self

Creates a new empty SignalCell suitable for use in static contexts.

Returns

• Self - An empty SignalCell with no signal stored.

pub fn set(&self, signal: Signal<T>)

Stores a signal into the cell.

Arguments

• Signal<T> - The signal to store.

Panics

Panics if a signal has already been stored.

pub fn get(&self) -> Signal<T>

Returns the signal stored in the cell.

Returns

• Signal<T> - The stored signal.

Panics

Panics if no signal has been stored via set.

impl<T> SignalCell<T>

where T: Clone + PartialEq + 'static,

pub fn get_mut_inner(&mut self) -> &mut UnsafeCell<Option<Signal<T>>>

impl<T> SignalCell<T>

where T: Clone + PartialEq + 'static,

pub fn new(inner: UnsafeCell<Option<Signal<T>>>) -> Self

Trait Implementations

impl<T> Debug for SignalCell<T>

where T: Clone + PartialEq + 'static,

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

Formats the value using the given formatter.

impl<T> Default for SignalCell<T>

where T: Clone + PartialEq + 'static,

Provides a default empty SignalCell.

Creates a SignalCell with None stored in the inner UnsafeCell.

Returns

• Self: An empty SignalCell with no signal stored.

fn default() -> Self

Returns the “default value” for a type.

impl<T> Sync for SignalCell<T>

where T: Clone + PartialEq + 'static,

Marks SignalCell as Sync for single-threaded WASM contexts.

SAFETY: SignalCell is only used in single-threaded WASM contexts. Concurrent access from multiple threads would be undefined behavior.
