Struct runa_wayland_protocols::wayland::wl_surface::v6::events::PreferredBufferScale

pub struct PreferredBufferScale {
    pub factor: i32,
}

preferred buffer scale for the surface

This event indicates the preferred buffer scale for this surface. It is sent whenever the compositor’s preference changes.

It is intended that scaling aware clients use this event to scale their content and use wl_surface.set_buffer_scale to indicate the scale they have rendered with. This allows clients to supply a higher detail buffer.

factor: i32

Implementations

impl PreferredBufferScale

pub const OPCODE: u16 = 2u16

Trait Implementations

impl Clone for PreferredBufferScale

fn clone(&self) -> PreferredBufferScale

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PreferredBufferScale

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for PreferredBufferScale

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<PreferredBufferScale> for PreferredBufferScale

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

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.
