Struct ReposeRuntime 

pub struct ReposeRuntime {

    pub sched: Scheduler,
    pub scale: f32,
    pub modifiers: Modifiers,
    pub mouse_pos_px: (f32, f32),
    pub pointer_inside: bool,

    pub frame_cache: Option<Frame>,
    pub textfield_states: HashMap<u64, Rc<RefCell<TextFieldState>>>,
    /* private fields */
}

Embeddable Repose runtime.

Manages composition scheduling, input routing, text-field state, and pointer/key dispatch. The host owns the event loop and GPU device; this is purely the UI logic layer.

Fields

sched: Scheduler

scale: f32

modifiers: Modifiers

mouse_pos_px: (f32, f32)

pointer_inside: bool

Whether the pointer is currently inside the window.

hover_id: Option<u64>

capture_id: Option<u64>

pressed_ids: HashSet<u64>

ime_preedit: bool

key_pressed_active: Option<u64>

last_focus: Option<u64>

frame_cache: Option<Frame>

textfield_states: HashMap<u64, Rc<RefCell<TextFieldState>>>

Implementations

impl ReposeRuntime

pub fn new() -> Self

pub fn set_viewport(&mut self, width_px: u32, height_px: u32)

Set the logical viewport size (in device pixels).

pub fn set_viewport_and_scale( &mut self, width_px: u32, height_px: u32, scale: f32, )

Set viewport size and DPI scale factor.

pub fn tick_animations(&self)

Advance animations. Call before compose each frame.

pub fn compose<F>( &mut self, root_fn: &mut F, render_ctx: &RenderContext, ) -> Frame

where F: FnMut(&mut Scheduler, &RenderContext) -> View,

Compose and layout a frame, returning the output for rendering.

Call tick_animations before this and cache_frame after (once you have applied any host-specific overlays like the devtools inspector).

pub fn frame( &mut self, root_fn: impl FnMut(&mut Scheduler, &RenderContext) -> View, render_ctx: &RenderContext, ) -> FrameOutput

Compose a frame and return structured output for the host.

pub fn cache_frame(&mut self, frame: Frame)

Store the composed frame for event hit testing.

pub fn handle_pointer_move(&mut self, pos: Vec2) -> PointerMoveResult

Process a pointer-move event. Returns cursor suggestion.

pub fn handle_pointer_press( &mut self, pos: Vec2, button: PointerButton, ) -> PointerButtonResult

Process a pointer button press. Returns focus/capture info.

pub fn handle_pointer_release(&mut self, pos: Vec2, _button: PointerButton)

Process a pointer button release.

pub fn handle_pointer_cancel(&mut self)

Cancel pointer state (focus lost, cursor left window, etc.).

pub fn clear_hover(&mut self)

Clear hover state, emitting HoverLeave for the currently hovered region.

pub fn reconcile_hover_from_mouse_pos(&mut self, new_frame: &Frame)

Reconcile hover state when the composed frame changes.

pub fn handle_scroll(&mut self, delta: Vec2) -> bool

Process a scroll event. Returns true if consumed.

pub fn handle_key(&mut self, event: &KeyEvent) -> bool

Process a keyboard key event. Returns true if consumed.

pub fn handle_ime(&mut self, event: &ImeEvent)

Process an IME event.

pub fn handle_focus_lost(&mut self)

Handle focus lost (window unfocused, etc.).

pub fn ensure_textfield_state( &mut self, key: u64, ) -> Rc<RefCell<TextFieldState>>

Get or create a text field state by its key.

pub fn tf_key_of(&self, visual_id: u64) -> u64

Look up the persistent state key for a visual hit-region id.

pub fn is_textfield(&self, id: u64) -> bool

True if the given id belongs to a TextField.

pub fn is_multiline(&self, id: u64) -> bool

True if the given textfield id is multiline.

pub fn paste_into_focused(&mut self, text: &str)

Insert text into a focused text field (used for paste).

pub fn cursor_suggestion(&self) -> Option<CursorIcon>

Get the cursor suggestion (set during pointer-move handling).

pub fn take_cursor_suggestion(&mut self) -> Option<CursorIcon>

Take the cursor suggestion (clears it).

Trait Implementations

impl Default for ReposeRuntime

fn default() -> Self

Returns the “default value” for a type.
