Checks if a target value is present in a collection using SIMD instructions. The suffix (x4, x8, x16, x32, x64) indicates the number of lanes processed simultaneously.

Note: Choose the variant matching your CPU's capabilities. Higher lane counts provide better performance but require newer CPU support.

go
// Using AVX2 variant (32 lanes at once) - Intel Haswell+ / AMD Excavator+
found := simd.ContainsInt8x32([]int8{1, 2, 3, 4, 5}, 3)
// true
go
// Using AVX variant (16 lanes at once) - works on all amd64
found := simd.ContainsInt64x2([]int64{1000000, 2000000, 3000000}, 2000000)
// true
go
// Using AVX-512 variant (64 lanes at once) - Intel Skylake-X+
found := simd.ContainsUint8x64([]uint8{10, 20, 30, 40, 50}, 30)
// true
go
// Float32 with AVX2 (8 lanes at once)
found := simd.ContainsFloat32x8([]float32{1.1, 2.2, 3.3, 4.4}, 3.3)
// true
go
// Empty collection returns false
found := simd.ContainsInt16x16([]int16{}, 5)
// false
