Module shape 

The geometry layer: where a shape’s parts land on the canvas, how big they are, and how they paint.

Deliberately document-agnostic. Every type here is handed the entities it draws — a block arrives with its pins, an image with its bytes, a text box with its measured extent — so nothing in this module looks anything up. The caller that knows the scope resolves those (see Drawing), which is also what keeps a pin drawn as a boundary port and the same pin drawn as a stub on its block from needing two data shapes.

Modules

area

block

image

pin

The pin vocabulary the geometry layer draws in: the document’s pin entity and its value enums, plus the derived readings the drawing and hit-test paths take off a pin’s registers.

text_box

Structs

PinLocation

ShapeLabel

A blockworx_doc::block_model::Label namespace resolved for drawing: its four registers read out, with the offset converted from the document’s fixed-point to the world pixels every anchor formula works in (shape_label is the one conversion). Borrowed and Copy, so a drag preview builds its shifted twin with a struct update instead of cloning the name.

Enums

Deletable

Something the user can delete: a shape (child block or boundary port), a route, a whole multi-selection of shapes, or a group of child-block pins.

RoleTarget

A shape that carries an accent role the picker can target: a child block, a boundary port, a route, a boundary area, or a text box.

ShapeId

A unified ID that can refer to a child block (BlockId), a port-pin on the current block (PinId), a free-floating text annotation (TextId), a boundary area (AreaId), a free-floating background image (ImageId), or a block’s foreground icon (keyed by the owning BlockId).

ShapeRef

A borrowed reference to any shape, bundled with whatever the geometry layer needs beside the entity itself: a block’s pins, a port’s own id, a text box’s measured extent, artwork’s bytes. Because this is a concrete enum (not a trait object), methods with generic parameters (e.g. with_pins) work naturally — dispatch is via match, not a vtable.

Traits

BaseShape

BaseShape is what every shape can answer without knowing the document: where it sits, what its labels are, where its pins hang, and how it paints. Writes are not here — they are commits, emitted by crate::edit against the document the gesture read.
