sourcepub fn new(buffer: &'buf mut [u8]) -> Self
pub fn new(buffer: &'buf mut [u8]) -> Self
Create a new, empty RecvAncillaryBuffer
from a raw byte buffer.
The buffer size may be computed with cmsg_space
, or it may be
zero for an empty buffer, however in that case, consider default()
instead, or even using recv
instead of recvmsg
.
§Examples
Allocate a buffer for a single file descriptor:
let mut space = [0; rustix::cmsg_space!(ScmRights(1))];
let mut cmsg_buffer = RecvAncillaryBuffer::new(&mut space);
Allocate a buffer for credentials:
let mut space = [0; rustix::cmsg_space!(ScmCredentials(1))];
let mut cmsg_buffer = RecvAncillaryBuffer::new(&mut space);
Allocate a buffer for two file descriptors and credentials:
let mut space = [0; rustix::cmsg_space!(ScmRights(2), ScmCredentials(1))];
let mut cmsg_buffer = RecvAncillaryBuffer::new(&mut space);
sourcepub fn drain(&mut self) -> AncillaryDrain<'_> ⓘ
pub fn drain(&mut self) -> AncillaryDrain<'_> ⓘ
Drain all messages from the buffer.
