Enum NodeContent 

pub enum NodeContent {
    Container,
    Text(TextId),
    Edit(Key),
    Image(ImageId, ImageOpts),
    Line(LineId),
    Cells(CellsId),
    Fragment(FragmentDrawId),
    Polygon(FragmentDrawId),
    Path(PathId),
}

Variants

Container

Text(TextId)

Edit(Key)

Editable text; retained state lives in the core’s EditStore.

Image(ImageId, ImageOpts)

A host-registered image (see Resources), drawn from the atlas or from a texture of its own as the entry’s backing says, met by its box as opts say.

Line(LineId)

A stroke through a run of points: one segment quad per straight piece (see crate::line). The node is a float sized to the stroke’s bounding box, so it takes no room, and its bg is the stroke colour. In its parent’s box space it paints in the parent’s layer at its place in the tree (NodeContent::drawn_in_parent).

Cells(CellsId)

A cell grid (see crate::cells): a terminal’s screen as one node.

Fragment(FragmentDrawId)

A box a registered WGSL function paints (see crate::fragment). The handle and the sixteen parameters live in the frame’s FragmentList; the node carries only where.

Polygon(FragmentDrawId)

A filled polygon: a float sized to its own bounding box like a line, painted by the stock polygon fragment whose draw sits in the frame’s FragmentList like any fragment’s, its bg the fill. No hit region, no access row.

Path(PathId)

A filled and/or stroked outline of any shape (see crate::path): a float sized to its own bounding box like a line, its ops in the frame’s PathStore, drawn as glyph-mask quads from the atlas. Its bg is the fill, its border width and colour the stroke.

Implementations

impl NodeContent

pub fn drawn_in_parent(self) -> bool

Whether this is a shape the core floats for its own reasons — a line, polygon or path, a float only so it takes no room in a row or column (ADR 0010 decision 5). Such a node is its parent’s content as a child is: the parent’s clip holds it (F78), and it paints in the parent’s layer at its place in the tree rather than opening a layer of its own (F123) — a glyph drawn into a title bar is not over a toast that opened before the bar did.
