Struct Keyframe 

pub struct Keyframe {
    pub at: Option<f32>,
    pub dx: Option<f32>,
    pub dy: Option<f32>,
    pub slots: Slots,
}

One stop. Every field is optional: at resolves by position, and a slot a stop doesn’t name is left to its neighbours. Derefs to its Slots, so stop.bg reads the slot.

Fields

at: Option<f32>

Position in the cycle, 0..=1; None spreads evenly.

dx: Option<f32>

An offset from where layout put the node, logical px, as an entrance’s dx/dy is (backlog F132): the node and its subtree are drawn and hit that far away at this stop. One left out is 0, the node’s own place, so a stop naming only dy bobs it upright.

dy: Option<f32>

slots: Slots

Width, height, bg, radius, opacity, rotate and scale — the slots an entrance names too.

Implementations

impl Keyframe

pub fn width(self, width: impl Into<Sizing>) -> Keyframe

A crate::spec::Sizing, or a number of px, as on a spec.

pub fn height(self, height: impl Into<Sizing>) -> Keyframe

A crate::spec::Sizing, or a number of px, as on a spec.

pub fn grow_width(self) -> Keyframe

width(Sizing::GROW), as on a spec.

pub fn grow_height(self) -> Keyframe

height(Sizing::GROW), as on a spec.

pub fn bg(self, bg: Color) -> Keyframe

pub fn radius(self, radius: f32) -> Keyframe

pub fn rotate(self, turns: f32) -> Keyframe

A turn in turns clockwise (ADR 0043), as on a spec.

pub fn scale(self, scale: f32) -> Keyframe

A uniform scale about the node’s pivot, as on a spec.

pub fn opacity(self, opacity: f32) -> Keyframe

impl Keyframe

pub fn at(self, at: f32) -> Keyframe

pub fn offset(self, dx: f32, dy: f32) -> Keyframe

This stop dx, dy px from where layout put the node (F132).

pub fn dx(self, dx: f32) -> Keyframe

This stop dx px across from the node’s place; dy stays 0.

pub fn dy(self, dy: f32) -> Keyframe

This stop dy px down from the node’s place; dx stays 0.

pub fn offsets(&self) -> bool

Whether the stop names a position.
