newtype SharedInt

An atomic integer reference backed by SharedArrayBuffer. Can be shared across worker threads via toSendable/fromSendable.

new :: Int -> Effect SharedInt

Create a new SharedInt initialized to the given value.

read :: SharedInt -> Effect Int

Atomically read the current value.

write :: SharedInt -> Int -> Effect Unit

Atomically write a new value.

add :: SharedInt -> Int -> Effect Int

Atomically add to the current value. Returns the OLD value.

sub :: SharedInt -> Int -> Effect Int

Atomically subtract from the current value. Returns the OLD value.

compareAndSwap :: SharedInt -> Int -> Int -> Effect Int

Atomic compare-and-swap. If current value equals expected, replace with replacement. Returns the old value.

modify :: SharedInt -> (Int -> Int) -> Effect Int

Atomically modify the value using a CAS loop. Retries until the CAS succeeds.

toSendable :: SharedInt -> SendWrapper SharedInt

Wrap for sending to a worker thread.

fromSendable :: SendWrapper SharedInt -> SharedInt

Unwrap after receiving on a worker thread.
