# 1.27.0[−][src]Function core::arch::x86_64::_mm_sha256rnds2_epu32

    pub unsafe fn _mm_sha256rnds2_epu32(
        a: __m128i,
        b: __m128i,
        k: __m128i
    ) -> __m128i

This is supported on x86-64 and target feature `sha` only.

Performs 2 rounds of SHA256 operation using an initial SHA256 state (C,D,G,H) from `a`, an initial SHA256 state (A,B,E,F) from `b`, and a pre-computed sum of the next 2 round message values (unsigned 32-bit integers) and the corresponding round constants from `k`, and store the updated SHA256 state (A,B,E,F) in dst.

## 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`)
