Type Definition packed_simd_2::u8x4

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.

source

pub fn rotate_right(self, n: u8x4) -> u8x4

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

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

pub fn wrapping_sum(self) -> u8

Horizontal wrapping sum of the vector elements.

The intrinsic performs a tree-reduction of the vector elements. That is, for an 8 element vector:

((x0 + x1) + (x2 + x3)) + ((x4 + x5) + (x6 + x7))

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

source

pub fn wrapping_product(self) -> u8

Horizontal wrapping product of the vector elements.

The intrinsic performs a tree-reduction of the vector elements. That is, for an 8 element vector:

((x0 * x1) * (x2 * x3)) * ((x4 * x5) * (x6 * x7))

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