Struct Feedback

pub struct Feedback {
    pub surface: Object,
    pub callback: NewId,
}

request presentation feedback information

Request presentation feedback for the current content submission on the given surface. This creates a new presentation_feedback object, which will deliver the feedback information once. If multiple presentation_feedback objects are created for the same submission, they will all deliver the same information.

For details on what information is returned, see the presentation_feedback interface.

Trait Implementations

impl Clone for Feedback

fn clone(&self) -> Feedback

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Feedback

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for Feedback

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 Feedback

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

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.
