Struct KeyframesBuilder 

pub struct KeyframesBuilder { /* private fields */ }

Builder that collects offset-keyed snapshots before compiling them into per-property tracks.

Duplicate offsets are merged as snapshots are inserted. If the same property appears more than once at an offset, the later value wins.

Implementations

impl KeyframesBuilder

pub fn new() -> Self

Creates an empty keyframe builder with default timing.

pub const fn timing(&self) -> &Timing

Returns the timing that will be attached to the finished keyframes.

pub const fn with_timing(self, timing: Timing) -> Self

Sets the timing attached to the finished keyframes.

pub fn at(self, offset: f32, snapshot: impl Into<PropertySnapshot>) -> Self

Inserts a property snapshot at a normalized offset.

pub fn opacity(self, offset: f32, value: f32) -> Self

Inserts an opacity keyframe.

pub fn scale(self, offset: f32, value: f32) -> Self

Inserts a uniform scale keyframe.

pub fn translation(self, offset: f32, x: f32, y: f32) -> Self

Inserts a translation keyframe.

pub fn background_color(self, offset: f32, value: Color) -> Self

Inserts a background color keyframe.

pub fn border_color(self, offset: f32, value: Color) -> Self

Inserts a border color keyframe.

pub fn text_color(self, offset: f32, value: Color) -> Self

Inserts a text color keyframe.

pub fn shadow(self, offset: f32, value: Shadow) -> Self

Inserts a shadow keyframe.

pub fn push_at(&mut self, offset: f32, snapshot: impl Into<PropertySnapshot>)

Inserts a property snapshot at a normalized offset.

pub fn push_many<I, S>(&mut self, frames: I)

where I: IntoIterator<Item = (f32, S)>, S: Into<PropertySnapshot>,

Inserts multiple property snapshots and normalizes them in one pass.

pub fn finish(self) -> Keyframes

Compiles the collected snapshots into per-property tracks.

Trait Implementations

impl Clone for KeyframesBuilder

fn clone(&self) -> KeyframesBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyframesBuilder

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

Formats the value using the given formatter.

impl Default for KeyframesBuilder

fn default() -> KeyframesBuilder

Returns the “default value” for a type.

impl PartialEq for KeyframesBuilder

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
