Struct ArcSwapStore 

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

Wait-free reads via arc_swap::ArcSwap.

• load(): wait-free, returns cloned T from a guard (no allocation).
• store(): allocates one Arc, atomically swaps.

Best for: read-99%/write-1% data like themes and capabilities.

Implementations

impl<T: Clone + Send + Sync> ArcSwapStore<T>

pub fn new(val: T) -> Self

Create a new store with an initial value.

pub fn load_ref(&self) -> Guard<Arc<T>>

Read without cloning — returns a guard that derefs to T.

Prefer this when you only need a short-lived reference.

Trait Implementations

impl<T: Clone + Send + Sync> ReadOptimized<T> for ArcSwapStore<T>

fn load(&self) -> T

Read the current value. Must be wait-free or lock-free.

fn store(&self, val: T)

Atomically replace the stored value.
