Struct Frame 

pub struct Frame {
    pub progress: f32,
    pub finished: bool,
    /* private fields */
}

The values an animation resolves to at one moment in time.

Fields

progress: f32

0..=1 through the whole clip, loops included.

finished: bool

True once the clip has run out of time. Always false while looping forever.

Implementations

impl Frame

pub fn new() -> Self

pub fn set(&mut self, prop: Prop, value: impl Into<AnimValue>)

Set a property, replacing any value already there. Later writers win, which is what layers a sequence’s overlapping tracks.

pub fn get(&self, prop: Prop) -> Option<AnimValue>

pub fn number(&self, prop: Prop) -> Option<f32>

pub fn number_or(&self, prop: Prop, fallback: f32) -> f32

The number, or fallback when the property isn’t animating.

pub fn color(&self, prop: Prop) -> Option<Hsla>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn iter(&self) -> impl Iterator<Item = (Prop, AnimValue)> + '_

pub fn clear(&mut self)

Empty it for reuse, keeping any spill capacity it earned.

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

Write every styled property onto an element.

Prop::X/Prop::Y become a relative inset: gpui elements are Position::Relative by default and taffy treats an inset on those as a paint-time correction, so the element slides without pushing its siblings around. Prop::Rotate, Prop::Scale and Prop::Custom are skipped — read those back yourself.

Trait Implementations

impl Clone for Frame

fn clone(&self) -> Frame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Frame

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

Formats the value using the given formatter.

impl Default for Frame

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Frame

fn eq(&self, other: &Self) -> bool

Compared by what it holds, not by where it holds it — two frames with the same properties are equal whether or not one of them spilled.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
