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