Trait wayland_commons::MessageGroup
[−]
[src]
pub trait MessageGroup: Sized { fn is_destructor(&self) -> bool; unsafe fn from_raw_c(
obj: *mut c_void,
opcode: u32,
args: *const wl_argument
) -> Result<Self, ()>; fn as_raw_c_in<F, T>(self, f: F) -> T
where
F: FnOnce(u32, &mut [wl_argument]) -> T; }
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
fn is_destructor(&self) -> bool
Whether this message is a destructor
If it is, once send or receive the associated object cannot be used any more.
unsafe fn from_raw_c(
obj: *mut c_void,
opcode: u32,
args: *const wl_argument
) -> Result<Self, ()>
obj: *mut c_void,
opcode: u32,
args: *const wl_argument
) -> Result<Self, ()>
Construct a message of this group from its C representation
fn as_raw_c_in<F, T>(self, f: F) -> T where
F: FnOnce(u32, &mut [wl_argument]) -> T,
F: FnOnce(u32, &mut [wl_argument]) -> T,
Build a C representation of this message
It can only be accessed from the provided closure, and this consumes the message.
