Enum ToolbarPlacement 

pub enum ToolbarPlacement {
    Automatic,
    Navigation,
    Principal,
    Primary,
    Secondary,
    Bottom,
}

Where an item sits on the chrome that carries it (docs/toolbars.md).

A placement is a role, never a surface. Which toolbar, navigation bar or column an item rides follows from the piece that declared it, so an app never spells that out twice.

Variants

Automatic

The natural spot on this chrome: after the leading group on a desktop toolbar, the trailing item group on a navigation bar, an IF_ROOM menu action on Android.

Navigation

The leading edge: a pane toggle, a control that reveals what is to its left.

Principal

Centered: a title accessory, a transport, a status readout.

Primary

Trailing, and the last thing a crowded chrome gives up.

Secondary

Trailing, and the first thing a crowded chrome folds into its overflow.

Bottom

A bottom bar where the platform has one (iOS toolbarItems, an Android bottom app bar); ToolbarPlacement::Secondary everywhere else.
