Struct PacketRc

pub struct PacketRc { /* private fields */ }

Implementations

impl PacketRc

pub fn new() -> Self

pub fn set_tcp(&mut self, header: &TcpHeader)

Set TCP headers for this packet. Will panic if the packet already has a header.

pub fn get_tcp(&self) -> Option<TcpHeader>

pub fn set_udp(&mut self, src: SocketAddrV4, dst: SocketAddrV4)

Set UDP headers for this packet. Will panic if the packet already has a header.

pub fn set_payload(&mut self, payload: &[u8], priority: FifoPacketPriority)

Set the packet payload. Will panic if the packet already has a payload.

pub fn get_payload(&self, buffer: &mut [u8]) -> usize

Copy the packet payload to a buffer. Will truncate if the buffer is not large enough.

pub fn copy_payload<'a>( &self, iovs: impl IntoIterator<Item = &'a IoVec>, mem: &mut MemoryManager, ) -> Result<usize, Errno>

Copy the payload to the managed process. Even if this returns an error, some unspecified number of bytes may have already been copied.

pub fn total_size(&self) -> usize

pub fn header_size(&self) -> usize

pub fn payload_size(&self) -> usize

pub fn add_status(&mut self, status: PacketStatus)

pub fn src_address(&self) -> SocketAddrV4

pub fn dst_address(&self) -> SocketAddrV4

pub fn priority(&self) -> FifoPacketPriority

pub fn from_raw(c_ptr: *mut Packet) -> Self

Transfers ownership of the given c_ptr reference into a new rust packet object.

pub fn into_inner(self) -> *mut Packet

Transfers ownership of the inner c_ptr reference to the caller while dropping the rust packet object.

pub fn borrow_inner(&self) -> *mut Packet

Trait Implementations

impl Clone for PacketRc

Clone the reference to the packet.

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PacketRc

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

Formats the value using the given formatter.

impl Drop for PacketRc

fn drop(&mut self)

Executes the destructor for this type.

impl From<PacketEventData> for PacketRc

fn from(data: PacketEventData) -> Self

Converts to this type from the input type.

impl PacketDisplay for PacketRc

fn display_bytes(&self, writer: impl Write) -> Result<()>

Write the packet bytes.

impl PartialEq for PacketRc

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

Tests for self and other values to be equal, and is used by ==.

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

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