Instead of manually searching for NUL, why not just use
CStr::from_ptr
? In fact, you should technically be usingOsString
here instead ofCString
, because the string comes from the operating system and not from another programming language. So you should declare the buf as aVec
, and then useOsString::from_vec
followed byto_string_lossy

i think returning a PathBuf is actually better than String here, and using OsString for that makes sense. that does mean that i do have to still search for the nul myself though, since OsString won't do that (it'll just create a string with a bunch of trailing nuls). going through CStr (and then being forced to allocate a copy into a second Vec) doesn't seem worth it to avoid that?
