Struct ListingEntry 

pub struct ListingEntry {
    pub path: PathBuf,
    pub is_dir: bool,
    pub icon_byte: u32,
    pub name_byte_len: u32,
}

One row of a listing, in the shape entry presentation needs: where it points and whether it is a directory.

This is the type the minor and both majors share. It exists because activation alone needs no dependency between them — the [ActivationPolicy] names major ids — but the entry data does: the mode has to know, per row, what to draw an icon for. Both majors already modelled this, differently (crate::oil::OilEntry as { name, is_dir }, crate::file_tree::FileTreeEntry as { path, depth, kind }), and converging those two onto this one is DL.6.

Fields

path: PathBuf

Path the row refers to. Absolute where the major knows the directory; otherwise a bare file name, which is enough for the icon lookup (it inspects only the file name and extension).

is_dir: bool

icon_byte: u32

Byte offset within the row where the icon is spliced.

0 for a flat listing (oil), whose rows are bare filenames. The file tree indents and prefixes an expand marker, so its icon anchors after those — at byte 0 the glyph would land to the left of the indent and the tree’s shape would collapse.

name_byte_len: u32

Byte length of the entry NAME, which begins at Self::icon_byte (the icon is virtual text and occupies no source byte).

Carried rather than re-derived, because neither the path nor the icon anchor is enough to recover it. path.file_name() is wrong for the tree’s root row, whose text is the whole path; and “icon_byte to end of line” needs the rope, which would put a per-publish as_string() of the entire listing on the actor thread to learn something both majors already computed when they rendered the row.
