# 1.27.0[−][src]Function core::arch::x86::_mm256_shuffle_epi32

    pub unsafe fn _mm256_shuffle_epi32(a: __m256i, imm8: i32) -> __m256i

This is supported on x86 and target feature `avx2` only.

Shuffle 32-bit integers in 128-bit lanes of `a` using the control in `imm8`.

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

## 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`)
