Struct AnimatedIcons 

pub struct AnimatedIcons;

The bundled pairs, as one constant each — the same shape of thing Icons is for the static set.

These are the ones this framework needs itself. An application that needs another authors it with AnimatedIconData::custom, which is the same door IconData::custom opens for a static mark.

Implementations

impl AnimatedIcons

pub const MENU_CLOSE: AnimatedIconData

Three bars ↔ a cross. A drawer’s button: 0.0 shut, 1.0 open.

pub const PLAY_PAUSE: AnimatedIconData

A triangle ↔ two bars. A transport control: 0.0 stopped, 1.0 playing.

It carries a direction: a play arrow points the way the reader reads, so it is turned round in a right-to-left order — and the pause it becomes is symmetrical, so nothing looks turned round at the end of it.

pub const ADD_CLOSE: AnimatedIconData

A plus ↔ a cross. An add button that becomes the way to put away what it opened: 0.0 add, 1.0 dismiss.

pub const EXPAND_COLLAPSE: AnimatedIconData

A chevron ↔ the same chevron, over. Down when shut, up when open.

pub fn all() -> impl Iterator<Item = (&'static str, AnimatedIconData)>

All four, with their names — for a picker, or for a test that wants to say something about every pair there is.
