Feature gate:
#![feature(unbounded_shifts)]
This is a tracking issue for ACP 428.
This adds shifts functions to the integer types that ignore type bounds when shifting, with out of range values for the
rhs
yielding the result of shifting the entire value out (0
for left shifts, and unsigned right shifts, and either0
or-1
for signed right shifts).Public API
