# [−][src]Trait num::traits::ops::checked::CheckedShr

    pub trait CheckedShr: Shr<u32, Output = Self> {
        fn checked_shr(&self, rhs: u32) -> Option<Self>;
    }

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

## Required methods

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

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

    use num_traits::CheckedShr;

    let x: u16 = 0x8000;

    assert_eq!(CheckedShr::checked_shr(&x, 0),  Some(0x8000));
    assert_eq!(CheckedShr::checked_shr(&x, 1),  Some(0x4000));
    assert_eq!(CheckedShr::checked_shr(&x, 15), Some(0x0001));
    assert_eq!(CheckedShr::checked_shr(&x, 16), None);

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
