Struct GetSubsurface

pub struct GetSubsurface {
    pub id: NewId,
    pub surface: Object,
    pub parent: Object,
}

give a surface the role sub-surface

Create a sub-surface interface for the given surface, and associate it with the given parent surface. This turns a plain wl_surface into a sub-surface.

The to-be sub-surface must not already have another role, and it must not have an existing wl_subsurface object. Otherwise the bad_surface protocol error is raised.

Adding sub-surfaces to a parent is a double-buffered operation on the parent (see wl_surface.commit). The effect of adding a sub-surface becomes visible on the next time the state of the parent surface is applied.

The parent surface must not be one of the child surface’s descendants, and the parent must be different from the child surface, otherwise the bad_parent protocol error is raised.

This request modifies the behaviour of wl_surface.commit request on the sub-surface, see the documentation on wl_subsurface interface.

Implementations

impl GetSubsurface

pub const OPCODE: u16 = 1u16

Trait Implementations

impl Clone for GetSubsurface

fn clone(&self) -> GetSubsurface

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GetSubsurface

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for GetSubsurface

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 GetSubsurface

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

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.
