pub fn exchange(
typed_array: &JsValue,
index: u32,
value: i32,
) -> Result<i32, JsValue>
Expand description
The static Atomics.exchange()
method stores a given value at a given
position in the array and returns the old value at that position.
This atomic operation guarantees that no other write happens
until the modified value is written back.
You should use exchange_bigint
to operate on a BigInt64Array
or a BigUint64Array
.
