Enum wayland_client::protocol::wl_surface::Event

#[non_exhaustive]pub enum Event {
    Enter {
        output: WlOutput,
    },
    Leave {
        output: WlOutput,
    },
}

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.

Enter

surface enters an output

This is emitted whenever a surface's creation, movement, or resizing results in some part of it being within the scanout region of an output.

Note that a surface may be overlapping with zero or more outputs.

Fields of Enter

output: WlOutput

Leave

surface leaves an output

This is emitted whenever a surface's creation, movement, or resizing results in it no longer having any part of it within the scanout region of an output.

Fields of Leave

output: WlOutput
