Subject: auto merge of #8308 : blake2-ppc/rust/str-slice-bytes, r=alexcrichton
X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=ca6385034c1ca269b0b797fa039d485f7f413959;p=rust.git

auto merge of #8308 : blake2-ppc/rust/str-slice-bytes, r=alexcrichton

`fn slice_bytes` is marked unsafe since it allows violating the valid
string encoding property; but the function did also allow extending the
lifetime of the slice by mistake, since it's returning `&str`.

Use the annotation `slice_bytes<'a>(&'a str, ...) -> &'a str` so
that all uses of `slice_bytes` are region checked correctly.
