I don't know if this is documented anywhere but this is the style used by all APIs that deal with the filesystem. Sometimes it even gets used when a
PathBuf
would have been the better choice when it comes to heap allocations, because it's nicer to use.The reason why this is the preferred method is that a bunch of things implement
AsRef<Path>
, including&str
, so it avoids the manual cast to&Path
or memcpy toPathBuf
.
