Trait bonsaidb::core::num_traits::WrappingShl
source · pub trait WrappingShl: Sized + Shl<usize, Output = Self> {
// Required method
fn wrapping_shl(&self, rhs: u32) -> Self;
}Expand description
Performs a left shift that does not panic.
Required Methods§
sourcefn 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.
