[−][src]Trait num_traits::ops::checked::CheckedShl

pub trait CheckedShl: Shl<u32, Output = Self> {
    fn checked_shl(&self, rhs: u32) -> Option<Self>;
}

Performs a left shift that returns None on shifts larger than the type width.

Required methods

`fn checked_shl(&self, rhs: u32) -> Option<Self>`

Checked shift left. Computes self << rhs, returning None if rhs is larger than or equal to the number of bits in self.

use num_traits::CheckedShl;

let x: u16 = 0x0001;

assert_eq!(CheckedShl::checked_shl(&x, 0),  Some(0x0001));
assert_eq!(CheckedShl::checked_shl(&x, 1),  Some(0x0002));
assert_eq!(CheckedShl::checked_shl(&x, 15), Some(0x8000));
assert_eq!(CheckedShl::checked_shl(&x, 16), None);
