impl usizex2

pub fn rotate_left(self, n: usizex2) -> usizex2

Shifts the bits of each lane to the left by the specified amount in the corresponding lane of n, wrapping the truncated bits to the end of the resulting integer.

Note: this is neither the same operation as << nor equivalent to slice::rotate_left.

impl usizex2

pub fn wrapping_sum(self) -> usize

If an operation overflows it returns the mathematical result modulo 2^n where n is the number of times it overflows.
