[−][src]Struct smoltcp::wire::Ipv4Packet
A read/write wrapper around an Internet Protocol version 4 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 IPv4 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 header length is greater
than total length.
The result of this check is invalidated by calling set_header_len and set_total_len.
pub fn into_inner(self) -> T
[src]
Consume the packet, returning the underlying buffer.
pub fn version(&self) -> u8
[src]
Return the version field.
pub fn header_len(&self) -> u8
[src]
Return the header length, in octets.
pub fn dscp(&self) -> u8
[src]
Return the Differential Services Code Point field.
pub fn ecn(&self) -> u8
[src]
Return the Explicit Congestion Notification field.
pub fn total_len(&self) -> u16
[src]
Return the total length field.
pub fn ident(&self) -> u16
[src]
Return the fragment identification field.
pub fn dont_frag(&self) -> bool
[src]
Return the "don't fragment" flag.
pub fn more_frags(&self) -> bool
[src]
Return the "more fragments" flag.
pub fn frag_offset(&self) -> u16
[src]
Return the fragment offset, in octets.
pub fn hop_limit(&self) -> u8
[src]
Return the time to live field.
pub fn protocol(&self) -> Protocol
[src]
Return the protocol field.
pub fn checksum(&self) -> u16
[src]
Return the header checksum field.
pub fn src_addr(&self) -> Address
[src]
Return the source address field.
pub fn dst_addr(&self) -> Address
[src]
Return the destination address field.
pub fn verify_checksum(&self) -> bool
[src]
impl<'a, T: AsRef<[u8]> + ?Sized> Packet<&'a T>
[src]
impl<T: AsRef<[u8]> + AsMut<[u8]>> Packet<T>

pub fn set_total_len(&mut self, value: u16)
[src]
Set the total length field.
pub fn set_ident(&mut self, value: u16)
[src]
Set the fragment identification field.
pub fn clear_flags(&mut self)
[src]
Clear the entire flags field.
pub fn set_dont_frag(&mut self, value: bool)
[src]
Set the "don't fragment" flag.
pub fn set_more_frags(&mut self, value: bool)
[src]
Set the "more fragments" flag.
pub fn set_frag_offset(&mut self, value: u16)
[src]
Set the fragment offset, in octets.
pub fn set_hop_limit(&mut self, value: u8)
[src]
Set the time to live field.
pub fn set_protocol(&mut self, value: Protocol)
[src]
Set the protocol field.
pub fn set_checksum(&mut self, value: u16)
[src]
Set the header checksum field.
pub fn set_src_addr(&mut self, value: Address)
[src]
Set the source address field.
pub fn set_dst_addr(&mut self, value: Address)
[src]
Set the destination address field.
pub fn fill_checksum(&mut self)
[src]

pub fn payload_mut(&mut self) -> &mut [u8]
[src]
Return a mutable pointer to the payload.
