Struct runa_wayland_protocols::stable::viewporter::wp_viewport::v1::requests::SetSource

pub struct SetSource {
    pub x: Fixed,
    pub y: Fixed,
    pub width: Fixed,
    pub height: Fixed,
}

set the source rectangle for cropping

Set the source rectangle of the associated wl_surface. See wp_viewport for the description, and relation to the wl_buffer size.

If all of x, y, width and height are -1.0, the source rectangle is unset instead. Any other set of values where width or height are zero or negative, or x or y are negative, raise the bad_value protocol error.

The crop and scale state is double-buffered state, and will be applied on the next wl_surface.commit.

Fields

x: Fixed

y: Fixed

width: Fixed

height: Fixed

Implementations

impl SetSource

pub const OPCODE: u16 = 1u16

Trait Implementations

impl Clone for SetSource

fn clone(&self) -> SetSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SetSource

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for SetSource

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<SetSource> for SetSource

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

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 SetSource

impl StructuralEq for SetSource

impl StructuralPartialEq for SetSource
