Struct smoltcp::wire::UdpPacket
[−]
[src]
pub struct UdpPacket<T: AsRef<[u8]>> { /* fields omitted */ }
A read/write wrapper around an User Datagram Protocol packet buffer.
Methods
impl<T: AsRef<[u8]>> Packet<T>
[src]
fn new(buffer: T) -> Result<Packet<T>, Error>
Wrap a buffer with an UDP packet. Returns an error if the buffer is too small to contain one.
fn into_inner(self) -> T
Consumes the packet, returning the underlying buffer.
fn src_port(&self) -> u16
Return the source port field.
fn dst_port(&self) -> u16
Return the destination port field.
fn len(&self) -> u16
Return the length field.
fn checksum(&self) -> u16
Return the checksum field.
fn verify_checksum(&self, src_addr: &IpAddress, dst_addr: &IpAddress) -> bool
Validate the packet checksum.
Panics
This function panics unless src_addr
and dst_addr
belong to the same family,
and that family is IPv4 or IPv6.
impl<'a, T: AsRef<[u8]> + ?Sized> Packet<&'a T>
[src]
impl<T: AsRef<[u8]> + AsMut<[u8]>> Packet<T>
[src]
fn set_src_port(&mut self, value: u16)
Set the source port field.
fn set_dst_port(&mut self, value: u16)
Set the destination port field.
fn set_len(&mut self, value: u16)
Set the length field.
fn set_checksum(&mut self, value: u16)
Set the checksum field.
fn fill_checksum(&mut self, src_addr: &IpAddress, dst_addr: &IpAddress)
Compute and fill in the header checksum.
Panics
This function panics unless src_addr
and dst_addr
belong to the same family,
and that family is IPv4 or IPv6.
impl<'a, T: AsRef<[u8]> + AsMut<[u8]> + ?Sized> Packet<&'a mut T>
[src]
fn payload_mut(&mut self) -> &mut [u8]
Return a mutable pointer to the payload.
