Trait num_traits::ops::wrapping::WrappingShr [−][src]
pub trait WrappingShr: Sized + Shr<usize, Output = Self> {
fn wrapping_shr(&self, rhs: u32) -> Self;
}Expand description
Performs a right shift that does not panic.
Required methods
fn wrapping_shr(&self, rhs: u32) -> Self
fn wrapping_shr(&self, rhs: u32) -> Self
Panic-free bitwise shift-right; 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.
