Enum wayland_protocols::xdg_shell::server::xdg_wm_base::Event[−][src]

#[non_exhaustive]
pub enum Event {
    Ping {
        serial: u32,
    },
}

Variants (Non-exhaustive)

This enum is marked as 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.

`Ping`

Fields

serial: u32

check if the client is alive

The ping event asks the client if it’s still alive. Pass the serial specified in the event back to the compositor by sending a “pong” request back with the specified serial. See xdg_wm_base.pong.

Compositors can use this to determine if the client is still alive. It’s unspecified what will happen if the client doesn’t respond to the ping request, or in what timeframe. Clients should try to respond in a reasonable amount of time.

A compositor is free to ping in any way it wants, but a client must always respond to any xdg_wm_base object it created.
