Struct FitState 

pub struct FitState {
    pub pending: bool,
    /* private fields */
}

Fit-state tracker shared by the editor viewport and the player embed: remembers the last fitted surface (+ artboard) and only refits on resize or explicit invalidation, so interactive zoom survives redraws.

Fields

pending: bool

Implementations

impl FitState

pub fn new() -> Self

pub fn with_surface(surface: DVec2) -> Self

Pre-seed the surface record (e.g. after an explicit fit call) so zoom anchors work even when the artboard was degenerate.

pub fn ensure( &mut self, view: &mut ViewTransform, surface: DVec2, artboard: DVec2, refit_on_resize: bool, ) -> bool

Refit view when the surface/artboard changed beyond 0.5 px or a fit was requested via FitState::request. Returns true when a refit ran. Pan gestures opt out by skipping this call.

refit_on_resize: the player embed refits on window resize (true); the editor viewport keeps the user’s zoom on resize (false) and only refits on first layout, artboard change, or explicit request.

pub fn request(&mut self)

Request a refit on the next FitState::ensure call (e.g. after a zoom-to-fit shortcut).

pub fn surface_size(&self) -> DVec2

pub fn zoom_centered(&self, view: &mut ViewTransform, factor: f64)

Zoom about the surface center; no-op before the first layout.

pub fn zoom_at(&self, view: &mut ViewTransform, screen_pos: DVec2, factor: f64)

Zoom about screen_pos; no-op before the first layout.
