}Expand description
A serialization trait, implemented by wayland message types.
We can’t use serde, because it doesn’t support passing file descriptors. Most of the serialization code is expected to be generated by scanner.
For now instead of a Serializer trait, we only serialize to bytes and fds, but this might change in the future.
Required Methods§
sourcefn serialize<Fds: Extend<OwnedFd>>(self, buf: &mut BytesMut, fds: &mut Fds)
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.
Panic
If there is not enough space in the buffer, this function should
panic - the user should have called poll_reserve before
serializing, so this indicates programming error. If self
contains file descriptors that aren’t OwnedFd, this function
panics too.
