Package: effect
Module: SynchronizedRef

SynchronizedRef.modify

Computes a return value and a new ref value atomically, stores the new value, and returns the computed result.

When to use

Use to derive a separate result and the next stored SynchronizedRef value from the same current value in one serialized pure update.

See

• modifyEffect for effectfully deriving both the result and next stored value
• modifySome for deriving a result and optionally updating the stored value
• updateAndGet for returning the new stored value instead of a separate result

Signature

declare const modify: { <A, B>(f: (a: A) => readonly [B, A]): (self: SynchronizedRef<A>) => Effect.Effect<B>; <A, B>(self: SynchronizedRef<A>, f: (a: A) => readonly [B, A]): Effect.Effect<B>; }
