Reports tail recursive methods without @tailrec
annotation which verifies that the method will be
compiled with
tail call optimization.
Note that a method must be effectively final
for this inspection to be shown.
Example:
def factorial(n: Long, acc: Long = 1): Long =
if (n <= 1) acc else factorial(n - 1, acc * n)
After the quick-fix is applied:
@tailrec
def factorial(n: Long, acc: Long = 1): Long =
if (n <= 1) acc else factorial(n - 1, acc * n)
