Function small_slice_eq 

unsafe fn small_slice_eq(x: &[u8], y: &[u8]) -> bool

🔬This is a nightly-only experimental API. (pattern #27721)

Available on AArch64 and target feature neon, or LoongArch64 and target feature lsx, or x86-64 and target feature sse2 only.

Compares short slices for equality.

It avoids a call to libc’s memcmp which is faster on long slices due to SIMD optimizations but it incurs a function call overhead.

Safety

Both slices must have the same length.
