Trait num_traits::ops::checked::CheckedShl [−][src]
pub trait CheckedShl: Sized + 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>
[src]
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);
