Module: SynchronizedRef

SynchronizedRef.getAndSet

Sets a new value atomically and returns the previous value, serialized by the ref’s semaphore.

When to use

Use to replace a SynchronizedRef with a known value when the previous value is also needed.

See

• set for setting a value without returning the previous value
• setAndGet for setting a value and returning the new value
• getAndUpdate for deriving the new value from the current value

Signature

declare const getAndSet: { <A>(value: A): (self: SynchronizedRef<A>) => Effect.Effect<A>; <A>(self: SynchronizedRef<A>, value: A): Effect.Effect<A>; }
