Available with target feature `sse2` only.
Expand description

Checks 16 byte chunks of text at a time. If the chunk contains something other than printable ASCII characters and newlines, the function falls back to the generic implementation. Otherwise it uses SSE2 intrinsics to quickly find all newlines.
