Returns a new vector where the value at index is replaced by new_value.

Panics

impl i32x4

pub fn rotate_left(self, n: i32x4) -> i32x4

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 i32x4

pub fn wrapping_sum(self) -> i32

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