pub trait WrappingShl: Sized + Shl<usize, Output = Self> {
// Required method
fn wrapping_shl(&self, rhs: u32) -> Self;
}
Expand description
Performs a left shift that does not panic.
Required Methods§
sourcefn wrapping_shl(&self, rhs: u32) -> Self
fn wrapping_shl(&self, rhs: u32) -> Self
Panic-free bitwise shift-left; yields self << mask(rhs)
,
where mask
removes any high order bits of rhs
that would
cause the shift to exceed the bitwidth of the type.
use num_traits::WrappingShl;
let x: u16 = 0x0001;
assert_eq!(WrappingShl::wrapping_shl(&x, 0), 0x0001);
assert_eq!(WrappingShl::wrapping_shl(&x, 1), 0x0002);
assert_eq!(WrappingShl::wrapping_shl(&x, 15), 0x8000);
assert_eq!(WrappingShl::wrapping_shl(&x, 16), 0x0001);
