Enum ButtonRole 

pub enum ButtonRole {
    Primary,
    Secondary,
    Destructive,
    Plain,
    Key,
}

What a button does. The role is a button’s whole appearance: an app never picks a fill, an ink, an edge or a radius for one.

Role	Use	Face
Primary	the one main action of a view	inverted: primary ink as the fill, the content surface as the label
Secondary	every other action	a raised control with a derived edge and primary ink
Destructive	deletes, removes or revokes something	the secondary face lettered in danger ink; filled only inside the confirmation step
Plain	inline text actions, toolbar glyphs, close buttons	nothing at rest, a lift of its ground under the pointer; a labelled one’s ink sits on its layout edge and its lift and hit area reach outward
Key	a keypad or keyboard key (a calculator digit, an on-screen key, a one-letter toggle)	a faint lift of its ground at rest, its label in Title

Every role has the control radius (radii.control): buttons are not pills.
