[−][src]Function js_sys::Atomics::exchange
pub fn exchange(
typed_array: &JsValue,
index: u32,
value: i32
) -> Result<i32, JsValue>
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.
