Trait wayland_client::commons::MessageGroup[−][src]

pub trait MessageGroup {
    fn is_destructor(&self) -> bool;

    unsafe fn from_raw_c(
        obj: *mut c_void, 
        opcode: u32, 
        args: *const wl_argument
    ) -> Result<Self, ()>;

}

A group of messages

This represents a group of message that can be serialized on the protocol wire. Typically the set of events or requests of a single interface.

Implementations of this trait are supposed to be generated using the wayland-scanner crate.

Required Methods

If it is, once send or receive the associated object cannot be used any more.

Construct a message of this group from its C representation

Build a C representation of this message

It can only be accessed from the provided closure, and this consumes the message.
