Struct RenderedRegion 

pub struct RenderedRegion {
    pub field: String,
    pub page: usize,
    pub rect: [f32; 4],
    pub span: Option<[usize; 2]>,
}

One schema field placement’s extent on a rendered page.

rect is [x0, y0, x1, y1] in PDF points with a bottom-left origin — the same final geometry the stamp spine writes to the widget /Rect, so the region and the rendered field describe the identical box.

field is not unique within the Vec that LiveSession::regions returns: a content field breaks into one entry per segment (paragraph, heading, whole code fence) and per page each segment touches, a scalar referenced at several plate sites yields one per site, and tracked content plus a bound widget yields both. Consumers group by field; every entry routes to that field. The whole-field box is derived — the union of a page’s span-bearing segment rects, so inter-paragraph whitespace stays uncovered (#829); the field_boxes helper (and LiveSession::field_boxes) owns that union so consumers need not reimplement it.

Fields

field: String

Quill schema field path, e.g. "signature_block" or "$cards.indorsement.1.from" — the author-facing field address (the card form is kind + 0-based ordinal, $cards.<kind>.<n>.<field>), not any backend widget name.

page: usize

0-based page index.

rect: [f32; 4]

[x0, y0, x1, y1], PDF points, bottom-left origin.

span: Option<[usize; 2]>

The content slice this box covers: USV [start, end) into the field’s Content for content ink (one segment’s range), None for a scalar reference site or a widget — geometry with no content address. Additive and optional: omitted from the wire when None.

Implementations

impl RenderedRegion

pub fn contains(&self, page: usize, x: f32, y: f32) -> bool

Whether the point (x, y, PDF points, bottom-left origin) on page falls inside this region, edges inclusive. The one point-in-region predicate every field_at hit-test shares, so a click at a region border resolves identically everywhere.
