    }

Expand description

Performs a left shift that does not panic.

## Required Methods§

source

#### 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);
