#[non_exhaustive]
pub enum Event<'a> {
    IconSize {
        size: i32,
    },
    Done,
}

Available on crate feature wayland and Linux only.

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.

IconSize

describes a supported & preferred icon size

This event indicates an icon size the compositor prefers to be available if the client has scalable icons and can render to any size.

When the ‘xdg_toplevel_icon_manager_v1’ object is created, the compositor may send one or more ‘icon_size’ events to describe the list of preferred icon sizes. If the compositor has no size preference, it may not send any ‘icon_size’ event, and it is up to the client to decide a suitable icon size.

A sequence of ‘icon_size’ events must be finished with a ‘done’ event. If the compositor has no size preferences, it must still send the ‘done’ event, without any preceding ‘icon_size’ events.

Fields

size: i32

the edge size of the square icon in surface-local coordinates, e.g. 64

Done

all information has been sent

This event is sent after all ‘icon_size’ events have been sent.
