Keywords: rust, rustlang, rust-lang, usad8

# [−][src]Function core::arch::arm::usad8

    pub unsafe fn usad8(a: int8x4_t, b: int8x4_t) -> u32

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on ARM only.

Sum of 8-bit absolute differences.

Returns the 8-bit unsigned equivalent of

res = abs(a[0] - b[0]) + abs(a[1] - b[1]) +

## 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`)
