# Struct core::arch::x86_64::__m128i 1.27.0[−][src]

    #[repr(simd)]
    pub struct __m128i(_, _);

This is supported on x86-64 only.

128-bit wide integer vector type, x86-specific

This type is the same as the `__m128i` type defined by Intel, representing a 128-bit SIMD register. Usage of this type typically corresponds to the `sse` and up target features for x86/x86_64.

Internally this type may be viewed as:

- `i8x16` - sixteen `i8` variables packed together
- `i16x8` - eight `i16` variables packed together
- `i32x4` - four `i32` variables packed together
- `i64x2` - two `i64` variables packed together

(as well as unsigned versions). Each intrinsic may interpret the internal bits differently, check the documentation of the intrinsic to see how it's being used.

Note that this means that an instance of `__m128i` typically just means a "bag of bits" which is left up to interpretation at the point of use.

Most intrinsics using `__m128i` are prefixed with `_mm_` and the integer types tend to correspond to suffixes like "epi8" or "epi32".

# Examples

    #[cfg(target_arch = "x86")]
    use std::arch::x86::*;
    #[cfg(target_arch = "x86_64")]
    use std::arch::x86_64::*;

    let all_bytes_zero = _mm_setzero_si128();
    let all_bytes_one = _mm_set1_epi8(1);
    let four_i32 = _mm_set_epi32(1, 2, 3, 4);Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
