Enum Request 

#[non_exhaustive]
pub enum Request<'a> {
    Destroy,
    CreateIcon {},
    SetIcon {
        toplevel: XdgToplevel,
        icon: Option<XdgToplevelIconV1>,
    },
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Destroy

destroy the toplevel icon manager

Destroy the toplevel icon manager. This does not destroy objects created with the manager.

This is a destructor, once sent this object cannot be used any longer.

CreateIcon

create a new icon instance

Creates a new icon object. This icon can then be attached to a xdg_toplevel via the ‘set_icon’ request.

SetIcon

set an icon on a toplevel window

This request assigns the icon ‘icon’ to ‘toplevel’, or clears the toplevel icon if ‘icon’ was null. This state is double-buffered and is applied on the next wl_surface.commit of the toplevel.

After making this call, the xdg_toplevel_icon_v1 provided as ‘icon’ can be destroyed by the client without ‘toplevel’ losing its icon. The xdg_toplevel_icon_v1 is immutable from this point, and any future attempts to change it must raise the ‘xdg_toplevel_icon_v1.immutable’ protocol error.

The compositor must set the toplevel icon from either the pixel data the icon provides, or by loading a stock icon using the icon name. See the description of ‘xdg_toplevel_icon_v1’ for details.

If ‘icon’ is set to null, the icon of the respective toplevel is reset to its default icon (usually the icon of the application, derived from its desktop-entry file, or a placeholder icon). If this request is passed an icon with no pixel buffers or icon name assigned, the icon must be reset just like if ‘icon’ was null.

Fields

toplevel: XdgToplevel
