Struct socket2::RecvFlags

pub struct RecvFlags(pub(crate) c_int);

Flags for incoming messages.

Flags provide additional information about incoming messages.

Tuple Fields

0: c_int

Implementations

impl RecvFlags

Unix-only API.

pub const fn is_end_of_record(self) -> bool

Check if the message terminates a record.

Not all socket types support the notion of records. For socket types that do support it (such as SEQPACKET), a record is terminated by sending a message with the end-of-record flag set.

On Unix this corresponds to the MSG_EOR flag.

pub const fn is_out_of_band(self) -> bool

Check if the message contains out-of-band data.

This is useful for protocols where you receive out-of-band data mixed in with the normal data stream.

On Unix this corresponds to the MSG_OOB flag.

pub const fn is_confirm(self) -> bool

Check if the confirm flag is set.

This is used by SocketCAN to indicate a frame was sent via the socket it is received on. This flag can be interpreted as a ‘transmission confirmation’.

On Unix this corresponds to the MSG_CONFIRM flag.

pub const fn is_dontroute(self) -> bool

Check if the don’t route flag is set.

This is used by SocketCAN to indicate a frame was created on the local host.

On Unix this corresponds to the MSG_DONTROUTE flag.

impl RecvFlags

pub const fn is_truncated(self) -> bool

Check if the message contains a truncated datagram.

This flag is only used for datagram-based sockets, not for stream sockets.

On Unix this corresponds to the MSG_TRUNC flag. On Windows this corresponds to the WSAEMSGSIZE error code.

Trait Implementations

impl Clone for RecvFlags

fn clone(&self) -> RecvFlags

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RecvFlags

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

Formats the value using the given formatter.

impl PartialEq for RecvFlags

fn eq(&self, other: &RecvFlags) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
