🔬 This is a nightly-only experimental API. (rustc_private

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
This is supported with target feature
sse2
only.Check 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.
