Struct I32x4 

pub struct I32x4(pub [i32; 4]);

4-lane vector of 32-bit signed integers (128-bit).

Common uses:

• Accumulated DCT results
• Intermediate filter calculations
• SAD accumulation

Tuple Fields

0: [i32; 4]

Implementations

impl I32x4

pub const fn zero() -> Self

Create a new vector with all lanes set to zero.

pub const fn splat(value: i32) -> Self

Create a new vector with all lanes set to the same value.

pub const fn from_array(arr: [i32; 4]) -> Self

Create a vector from an array.

pub const fn to_array(self) -> [i32; 4]

Convert to an array.

pub fn horizontal_sum(self) -> i32

Horizontal sum of all elements.

pub fn narrow_sat(self, high: Self) -> I16x8

Narrow to I16x8 with another I32x4 (saturating).

pub const fn as_ptr(&self) -> *const i32

Get a pointer to the underlying array.

pub fn as_mut_ptr(&mut self) -> *mut i32

Get a mutable pointer to the underlying array.

pub fn iter(&self) -> Iter<'_, i32>

Get an iterator over the elements.

Trait Implementations

impl Add for I32x4

type Output = I32x4

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for I32x4

fn clone(&self) -> I32x4

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for I32x4

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for I32x4

fn default() -> I32x4

Returns the “default value” for a type.

impl Index<usize> for I32x4

type Output = i32

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for I32x4

fn index_mut(&mut self, index: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl PartialEq for I32x4

fn eq(&self, other: &I32x4) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Sub for I32x4

type Output = I32x4

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.
