Module paths

Logical paths are interpreted relative to a source or output root, never passed directly to the host OS.

Functions

has_symlinked_ancestor

hex

Render bytes as lowercase hex (used for digests).

join_under

logical_parent

Absolute parent directory of a logical path (/ for top-level entries).

normalize_absolute
