Enum ToolbarItemKind

What a toolbar item IS. The variants are the vocabulary every desktop toolbar shares; each backend realizes one with its native control, never with a drawn imitation.

Variants

Button

A push button running the item’s action.

Toggle

A two-state button. on seeds it; the user flipping it emits ToolbarValue::On, and the app’s own writes arrive as ToolbarPatch::On.

Fields

on: bool

Menu

A button that drops a menu — the same MenuItem model the menu bar uses, so a toolbar menu and its menu-bar twin are one list of commands.

Fields

items: Vec<MenuItem>

Search

A search field. Edits emit ToolbarValue::Text; the app’s own writes arrive as ToolbarPatch::Text.

Fields

text: String

placeholder: String

Label

Static text, for a status or a caption.

Separator

A divider, where the platform draws one (macOS toolbars have no separator, so AppKit renders it as a fixed space — docs/toolbars.md).

Space

A fixed gap.

FlexibleSpace

A gap that absorbs the leftover width. This is how the model expresses each platform’s packing: items before the first flexible space are leading, items after it trailing — GTK packs them start/end, XAML splits them across Content/PrimaryCommands, and AppKit and Qt place a real expanding spacer.

Trait Implementations

impl Clone for ToolbarItemKind

fn clone(&self) -> ToolbarItemKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ToolbarItemKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ToolbarItemKind

fn eq(&self, other: &ToolbarItemKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
