fn basename(p: &[u8]) -> String

Returns the last path component as a new String, ignoring trailing slashes. "a/b/c" → "c", "/foo" → "foo", "foo/" → "foo", "/" → "/", "" → "".

fn dirname(p: &[u8]) -> String

Returns the directory portion of p as a new String, ignoring trailing slashes. "a/b/c" → "a/b", "/foo/bar" → "/foo", "foo" → ".", "/" → "/", "" → ".".

fn extension(p: &[u8]) -> String

Returns the file extension of the last component including the dot, or "" if none. "foo.txt" → ".txt", "archive.tar.gz" → ".gz", "Makefile" → ""; dotfiles such as ".bashrc" have no extension.

fn is_absolute(p: &[u8]) -> bool

Returns true if p starts with /; the empty path is not absolute.

fn is_relative(p: &[u8]) -> bool

Returns true if p is not absolute.

fn join(a: &[u8], b: &[u8]) -> String

Joins two path components with a single /, returning a new String. join("a/b", "c") → "a/b/c", join("a/b/", "c") → "a/b/c". If b is absolute it replaces a (POSIX semantics).

fn join_into(base: &mut String, component: &[u8]) -> void

Appends component to base in place, inserting a / separator if needed. If component is absolute it replaces base entirely (POSIX semantics).

fn normalize(p: &[u8]) -> String

Normalizes p lexically: collapses //, drops . segments, resolves .. (no FS access). Matches Go path.Clean / Python posixpath.normpath: .. cannot escape root on absolute paths but is preserved on relative ones ("/../a" → "/a", "../a/../b" → "../b"); "" → "."; a trailing / is dropped unless the result is exactly "/". Segment tracking is capped at 256 deep; .. may mis-resolve beyond that.

fn stem(p: &[u8]) -> String

Returns the basename of p without its extension. "foo.txt" → "foo", "archive.tar.gz" → "archive.tar", ".bashrc" → ".bashrc".
