Trait num_traits::ops::checked::CheckedShr [−][src]
pub trait CheckedShr: Sized + Shr<u32, Output = Self> {
fn checked_shr(&self, rhs: u32) -> Option<Self>;
}Expand description
Performs a right shift that returns None on shifts larger than
the type width.
Required methods
fn checked_shr(&self, rhs: u32) -> Option<Self>
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.
