[−][src]Struct ethox::wire::UdpPacket
A read/write wrapper around an User Datagram Protocol packet buffer.
Methods
impl<T: AsRef<[u8]>> Packet<T>
[src]
pub fn new_unchecked(buffer: T) -> Packet<T>
[src]
Imbue a raw octet buffer with UDP packet structure.
pub fn new_checked(buffer: T) -> Result<Packet<T>>
[src]
Shorthand for a combination of new_unchecked and check_len.
pub fn check_len(&self) -> Result<()>
[src]
Ensure that no accessor method will panic if called.
Returns Err(Error::Truncated)
if the buffer is too short.
Returns Err(Error::Malformed)
if the length field has a value smaller
than the header length.
The result of this check is invalidated by calling set_len.
pub fn into_inner(self) -> T
[src]
Consume the packet, returning the underlying buffer.
pub fn src_port(&self) -> u16
[src]
Return the source port field.
pub fn dst_port(&self) -> u16
[src]
Return the destination port field.
pub fn len(&self) -> u16
[src]
Return the length field.
pub fn checksum(&self) -> u16
[src]
Return the checksum field.
pub fn verify_checksum(
&self,
src_addr: &IpAddress,
dst_addr: &IpAddress
) -> bool
[src]
&self,
src_addr: &IpAddress,
dst_addr: &IpAddress
) -> bool
impl<'a, T: AsRef<[u8]> + ?Sized> Packet<&'a T>
[src]
impl<T: AsRef<[u8]> + AsMut<[u8]>> Packet<T>
[src]
pub fn set_src_port(&mut self, value: u16)
[src]
Set the source port field.
pub fn set_dst_port(&mut self, value: u16)
[src]
Set the destination port field.
pub fn set_len(&mut self, value: u16)
[src]
Set the length field.
pub fn set_checksum(&mut self, value: u16)
[src]
Set the checksum field.
pub fn fill_checksum(&mut self, src_addr: &IpAddress, dst_addr: &IpAddress)
[src]
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.
pub fn payload_mut(&mut self) -> &mut [u8]
[src]
Return a mutable pointer to the payload.
