Module status_bubble 

A transient floating status bubble: a small floating Panel that appears when a status changes (a page turn, a zoom step, a sync that finished) or while the pointer rests on its corner, then fades away.

Transient by contract: it is shown on change and hides on its own. What a person needs to read at any time (the cursor’s line and column, a word count, conflict counts) is persistent status and belongs in crate::chrome::status_bar, which reserves its band. A capture never forces the bubble open; only a screenshot scenario that stages the change shows it.

The bubble floats in the bottom-trailing corner of the area it reports on, one gutter in, clear of the content’s leading edge. It owns its text, its timing and its paint; the app says what changed.

Structs

SaveStatusSurface

A document’s save status, on the framework’s status surfaces (HIG §7c): “Saving…” and “Saved” are a change worth noticing once, so they show in the transient StatusBubble; a failed save is an error the person must act on, so it is an error toast (danger icon, the reason, a “Try again” action and a close button) that stays until the save succeeds or it is dismissed. An app reports the state and routes clicks; it never pins a bubble open or paints its own save pill.

StatusBubble

Every method takes an explicit now: Instant, so a test drives the whole show → linger → fade → hide cycle without a wall clock.

Enums

SaveAction

What a person did on the save status surface.

SaveState

What a document’s save state is, as the save status surface shows it.

Constants

DEFAULT_LINGER

How long the bubble lingers after a poke (or after the pointer leaves its zone) before it fades out, absent any new activity.

Functions

draw_pill

Paint a bubble with text in rect: a floating Panel (the blurred material, one soft shadow) with the label centred. For a bubble that hosts controls beside its label; a plain status uses StatusBubble::paint.

pill_height

Height shared by layout reservations and the rendered pill: the label’s line box plus the pill’s vertical padding, never below a Small control.

pill_size

The pill’s size for text. control is a leading+trailing slot in px each for a control inside the pill (0.0 for a plain label).
