Struct runa_wayland_protocols::stable::xdg_shell::xdg_toplevel::v5::requests::SetMaxSize

pub struct SetMaxSize {
    pub width: i32,
    pub height: i32,
}

set the maximum size

Set a maximum size for the window.

The client can specify a maximum size so that the compositor does not try to configure the window beyond this size.

The width and height arguments are in window geometry coordinates. See xdg_surface.set_window_geometry.

Values set in this way are double-buffered. They will get applied on the next commit.

The compositor can use this information to allow or disallow different states like maximize or fullscreen and draw accurate animations.

Similarly, a tiling window manager may use this information to place and resize client windows in a more effective way.

The client should not rely on the compositor to obey the maximum size. The compositor may decide to ignore the values set by the client and request a larger size.

If never set, or a value of zero in the request, means that the client has no expected maximum size in the given dimension. As a result, a client wishing to reset the maximum size to an unspecified state can use zero for width and height in the request.

Requesting a maximum size to be smaller than the minimum size of a surface is illegal and will result in an invalid_size error.

The width and height must be greater than or equal to zero. Using strictly negative values for width or height will result in a invalid_size error.

Fields

width: i32

height: i32

Implementations

impl SetMaxSize

pub const OPCODE: u16 = 7u16

Trait Implementations

impl Clone for SetMaxSize

fn clone(&self) -> SetMaxSize

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SetMaxSize

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for SetMaxSize

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<SetMaxSize> for SetMaxSize

fn eq(&self, other: &SetMaxSize) -> 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 SetMaxSize

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.
