No way to portably find if OsStr has a particular prefix · Issue #22741 · rust-lang/rust (original) (raw)

This is essentially the operation provided by starts_with() on String, str, and slice.

Right now, this can only be done by either:

• requiring the OsStr to be utf-8 (and converting it to str/String)
• Or depending on the unix-only as_bytes() method on OsStrExt
