pub fn all<T: IntoAll>(futures: T) -> All<T::Branches> ⓘExpand description
Runs animations at the same time and completes when all of them have.
Takes a tuple of up to 12 futures of any types (all((a, b, c))), or any
number of futures of one type: a Vec, an array or an iterator, e.g.
all(cards.iter().map(|c| c.fade_in())). Returns their outputs (a tuple
or a Vec).
Every branch starts at the same time; afterwards the task continues from the latest end time among them.
