In atomicintยง
See primary documentation in context for infix โ-=.
multi infix:<โ-=>(atomicint $ is rw, int $value) multi infix:<โ-=>(atomicint $ is rw, Int() $value)
Performs an atomic subtraction on a native integer. This will be performed using hardware-provided atomic operations. Since the operation is atomic, it is safe to use without acquiring a lock. Evaluates to the result of the subtraction. Underflow will wrap around silently. If $value
is too big to unbox to a 64-bit integer, an exception will be thrown. If $value
otherwise overflows atomicint
then it will be silently truncated before the subtraction is performed.
