Struct runa_wayland_protocols::stable::xdg_shell::xdg_wm_base::v5::events::Ping

pub struct Ping {
    pub 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. The “unresponsive” error is provided for compositors that wish to disconnect unresponsive clients.

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.

Trait Implementations

impl Clone for Ping

fn clone(&self) -> Ping

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Ping

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for Ping

fn deserialize(data: &'a [u8], fds: &'a [RawFd]) -> Result<Self, Error>

Deserialize from the given buffer. Returns deserialized message, and number of bytes and file descriptors consumed, respectively.

impl PartialEq<Ping> for Ping

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Ping

fn serialize<Fds: Extend<OwnedFd>>(self, buf: &mut BytesMut, fds: &mut Fds)

Serialize into the buffered writer. This function returns no errors, failures in seializing are generally program errors, and triggers panicking.

fn len(&self) -> u16

How many bytes will this message serialize to. Including the 8 byte header.

fn nfds(&self) -> u8

How many file descriptors will this message serialize to.
