Enum Payload 

pub enum Payload {
    None,
    Bool,
    Index,
    Number,
}

What a widget hands its message constructor when it fires.

A Button holds an M. A Checkbox holds a fn(bool) -> M, a List a fn(usize) -> M, a Slider a fn(f32) -> M. An engine resolving a name from a file into the application’s message type has to know which, so the descriptor says.

Variants

None

The widget holds the message itself: M.

Bool

fn(bool) -> M — a checkbox, a toggle, a collapse.

Index

fn(usize) -> M — anything that selects one of several.

Number

fn(f32) -> M — a slider, a rating.
