Struct SetPosition

pub struct SetPosition {
    pub x: i32,
    pub y: i32,
}

reposition the sub-surface

This schedules a sub-surface position change. The sub-surface will be moved so that its origin (top left corner pixel) will be at the location x, y of the parent surface coordinate system. The coordinates are not restricted to the parent surface area. Negative values are allowed.

The scheduled coordinates will take effect whenever the state of the parent surface is applied. When this happens depends on whether the parent surface is in synchronized mode or not. See wl_subsurface.set_sync and wl_subsurface.set_desync for details.

If more than one set_position request is invoked by the client before the commit of the parent surface, the position of a new request always replaces the scheduled position from any previous request.

The initial position is 0, 0.

Trait Implementations

impl Clone for SetPosition

fn clone(&self) -> SetPosition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SetPosition

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for SetPosition

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 for SetPosition

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for SetPosition

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.

impl Eq for SetPosition
