RecvFlags

rama::net::socket::core

Struct RecvFlags 

pub struct RecvFlags(/* private fields */);
Expand description

Flags for incoming messages.

Flags provide additional information about incoming messages.

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.
