Struct runa_wayland_protocols::stable::xdg_shell::xdg_toplevel::v5::events::WmCapabilities

pub struct WmCapabilities<'a> {
    pub capabilities: &'a [u8],
}

compositor capabilities

This event advertises the capabilities supported by the compositor. If a capability isn’t supported, clients should hide or disable the UI elements that expose this functionality. For instance, if the compositor doesn’t advertise support for minimized toplevels, a button triggering the set_minimized request should not be displayed.

The compositor will ignore requests it doesn’t support. For instance, a compositor which doesn’t advertise support for minimized will ignore set_minimized requests.

Compositors must send this event once before the first xdg_surface.configure event. When the capabilities change, compositors must send this event again and then send an xdg_surface.configure event.

The configured state should not be applied immediately. See xdg_surface.configure for details.

The capabilities are sent as an array of 32-bit unsigned integers in native endianness.

Implementations

impl<'a> WmCapabilities<'a>

pub const OPCODE: u16 = 3u16

Trait Implementations

impl<'a> Clone for WmCapabilities<'a>

fn clone(&self) -> WmCapabilities<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for WmCapabilities<'a>

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for WmCapabilities<'a>

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<'a> PartialEq<WmCapabilities<'a>> for WmCapabilities<'a>

fn eq(&self, other: &WmCapabilities<'a>) -> 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<'a> Serialize for WmCapabilities<'a>

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.
