[−][src]Macro safe_arch::extract_m128i_m256i

macro_rules! extract_m128i_m256i {
    ($a:expr, $imm:expr) => { ... };
}
This is supported with target feature avx2 only.

Gets an m128i value out of an m256i.

The lane to get must be a constant. Only the lowest bit of the value is used.

let a = m256i::from([5_u128, 6_u128]);
//
assert_eq!(extract_m128i_m256i!(a, 0), m128i::from(5_u128));
assert_eq!(extract_m128i_m256i!(a, 1), m128i::from(6_u128));
// the index is "wrapped" to be in bounds.
assert_eq!(extract_m128i_m256i!(a, 2), m128i::from(5_u128));
