Struct Frame 

pub struct Frame { /* private fields */ }

A read-only presentation snapshot. It owns no tasks or GPUI resources.

Implementations

impl Frame

pub fn at(target: Target) -> Self

Creates a static presentation, useful for scroll, drag, and custom value bindings.

pub fn just_completed(self) -> bool

Completion edge. Read once per view render to dispatch an owner-level event.

pub fn target(self) -> Target

Current presentation values, rather than the declaration’s destination.

pub fn velocity(self) -> [f64; 3]

Current x, y, and opacity velocities per second, before drawing clamps.

pub fn layout_velocity(self) -> [Option<f64>; 3]

Width, height, and radius velocities in logical pixels per second. Undeclared channels return None; velocities are before drawing clamps.

pub fn presence(self) -> Presence

Current lifecycle phase.

pub fn is_animating(self) -> bool

Whether another animation frame is needed.

pub fn is_mounted(self) -> bool

Whether the element must remain in the rendered tree, including its exit.

pub fn is_present(self) -> bool

Whether the model requests presence. Disable exit-time input using this.

impl Frame

pub fn apply<E: Styled>(self, element: E) -> E

Applies opacity, relative left/top insets, and declared width, height, and radius to a styled element. Sizes cause real layout reflow; these are not GPU transforms or layout projection. Undeclared layout properties preserve the element’s style. Radius does not enable overflow clipping. This replaces the div’s position mode and left/top values. Use a wrapper if the div itself needs absolute positioning. Normal layout space remains reserved until exit completes; siblings do not move with these offsets.

pub fn render<E: IntoElement>(self, build: impl FnOnce(Self) -> E) -> AnyElement

Builds an element only while mounted, retaining it throughout exit. Continue declaring this every render even when present(false). This does not disable handlers or transfer focus during exit: the owner must guard input using is_present() and restore focus before removal.

Trait Implementations

impl Clone for Frame

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Frame

impl Debug for Frame

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
