Struct wayland_commons::wire::Message

pub struct Message {
    pub sender_id: u32,
    pub opcode: u16,
    pub args: SmallVec<[Argument; 4]>,
}

A wire message

Fields

sender_id: u32

ID of the object sending this message

opcode: u16

Opcode of the message

args: SmallVec<[Argument; 4]>

Arguments of the message

Implementations

impl Message

pub fn write_to_buffers(
    &self,
    payload: &mut [u32],
    fds: &mut [RawFd]
) -> Result<(usize, usize), MessageWriteError>

Serialize the contents of this message into provided buffers

Returns the number of elements written in each buffer

Any serialized Fd will be dup()-ed in the process

pub fn from_raw<'a, 'b>(
    raw: &'a [u32],
    signature: &[ArgumentType],
    fds: &'b [RawFd]
) -> Result<(Message, &'a [u32], &'b [RawFd]), MessageParseError>

Attempts to parse a single wayland message with the given signature.

If the buffers contains several messages, only the first one will be parsed, and the unused tail of the buffers is returned. If a single message was present, the returned slices should thus be empty.

Errors if the message is malformed.

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl PartialEq<Message> for Message

fn eq(&self, other: &Message) -> 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.
