Struct BubbleState 

pub struct BubbleState {
    visibility: Mutex<BubbleVisibility>,
    last_position: Mutex<Option<BubblePosition>>,
}

Tauri-managed state for the webcam-bubble window (M-BUBBLE.0 / AUT-273 + M-BUBBLE.3 / AUT-276). Tracks both the visibility state machine and the in-memory last-known position so position persistence survives hide/show cycles.

last_position = None means “no remembered position — first-show will compute a sensible default.” Once set (either by loading from disk on first show, by WindowEvent::Moved mid-session, or by set_last_position for tests), the value is the source of truth for the next show.

Fields

visibility: Mutex<BubbleVisibility>

last_position: Mutex<Option<BubblePosition>>

Implementations

impl BubbleState

pub fn last_position(&self) -> Option<BubblePosition>

Snapshot the current remembered position (or None if unset). Used by the WindowEvent::Moved handler in main.rs to keep the in-memory cache fresh during drags.

pub fn set_last_position(&self, pos: BubblePosition)

Replace the remembered position. Cheap (one mutex acquire + an i32 pair copy) so safe to call on every WindowEvent::Moved.

Trait Implementations

impl Default for BubbleState

fn default() -> BubbleState

Returns the “default value” for a type.
