Struct Xmm 

#[repr(C)]
pub struct Xmm(pub [u8; 16]);

The 128 bits of one SSE (xmm) register.

Stored as raw little-endian bytes; the helpers read and build them as scalars or packed lanes.

Tuple Fields

0: [u8; 16]

Implementations

impl Xmm

pub const ZERO: Xmm

An all-zero register.

pub fn to_bytes(self) -> [u8; 16]

Returns the raw little-endian bytes.

pub fn from_bytes(bytes: [u8; 16]) -> Xmm

Builds a register from raw little-endian bytes.

pub fn u128(self) -> u128

Returns all 128 bits as an unsigned integer.

pub fn from_u128(value: u128) -> Xmm

Builds a register from a 128-bit unsigned integer.

pub fn f32(self) -> f32

Returns the low lane as an f32, a scalar single as after movss.

pub fn f64(self) -> f64

Returns the low lane as an f64, a scalar double as after movsd.

pub fn f32x4(self) -> [f32; 4]

Returns the four packed f32 lanes.

pub fn f64x2(self) -> [f64; 2]

Returns the two packed f64 lanes.

pub fn i32x4(self) -> [i32; 4]

Returns the four packed i32 lanes.

pub fn u64x2(self) -> [u64; 2]

Returns the two packed u64 lanes.

pub fn set_f32(&mut self, value: f32)

Sets the low f32 lane, leaving the rest unchanged.

pub fn set_f64(&mut self, value: f64)

Sets the low f64 lane, leaving the rest unchanged.

pub fn from_f32(value: f32) -> Xmm

Builds a register with value in the low f32 lane and zeros elsewhere.

pub fn from_f64(value: f64) -> Xmm

Builds a register with value in the low f64 lane and zeros elsewhere.

pub fn from_f32x4(lanes: [f32; 4]) -> Xmm

Builds a register from four packed f32 lanes.

pub fn from_f64x2(lanes: [f64; 2]) -> Xmm

Builds a register from two packed f64 lanes.
