data WeakMap t0 t1

Keys must be native objects (including functions); primitive keys throw, as they do in the JavaScript WeakMap API.

new :: forall key value. Effect (WeakMap key value)

get :: forall key value. key -> WeakMap key value -> Effect (Nullable value)

set :: forall key value. key -> value -> WeakMap key value -> Effect Unit

delete :: forall key value. key -> WeakMap key value -> Effect Boolean

has :: forall key value. key -> WeakMap key value -> Effect Boolean
