Struct MultiHeaders

pub struct MultiHeaders<S> {
    items: Box<[mmsghdr]>,
    addresses: Box<[MaybeUninit<S>]>,
    _cmsg_buffers: Option<Box<[u8]>>,
    msg_controllen: usize,
}

Preallocated structures needed for recvmmsg and sendmmsg functions

Fields

items: Box<[mmsghdr]>

addresses: Box<[MaybeUninit<S>]>

_cmsg_buffers: Option<Box<[u8]>>

msg_controllen: usize

Implementations

impl<S> MultiHeaders<S>

pub fn preallocate(num_slices: usize, cmsg_buffer: Option<Vec<u8>>) -> Self

where S: Copy + SockaddrLike,

Preallocate structure used by recvmmsg and sendmmsg takes number of headers to preallocate

cmsg_buffer should be created with cmsg_space! if needed

Trait Implementations

impl<S: Debug> Debug for MultiHeaders<S>

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

Formats the value using the given formatter.
