Struct smoltcp::wire::Icmpv4Packet [−][src]
A read/write wrapper around an Internet Control Message Protocol version 4 packet buffer.
Implementations
impl<T: AsRef<[u8]>> Packet<T>
[src]
pub fn new_unchecked(buffer: T) -> Packet<T>
[src]
Imbue a raw octet buffer with ICMPv4 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.
The result of this check is invalidated by calling set_header_len.
pub fn into_inner(self) -> T
[src]
Consume the packet, returning the underlying buffer.
pub fn msg_type(&self) -> Message
[src]
Return the message type field.
pub fn msg_code(&self) -> u8
[src]
Return the message code field.
pub fn checksum(&self) -> u16
[src]
Return the checksum field.
pub fn echo_ident(&self) -> u16
[src]
Return the identifier field (for echo request and reply packets).
Panics
This function may panic if this packet is not an echo request or reply packet.
pub fn echo_seq_no(&self) -> u16
[src]
Return the sequence number field (for echo request and reply packets).
Panics
This function may panic if this packet is not an echo request or reply packet.
pub fn header_len(&self) -> usize
[src]
Return the header length. The result depends on the value of the message type 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>
[src]
pub fn set_msg_type(&mut self, value: Message)
[src]
Set the message type field.
pub fn set_msg_code(&mut self, value: u8)
[src]
Set the message code field.
pub fn set_checksum(&mut self, value: u16)
[src]
Set the checksum field.
pub fn set_echo_ident(&mut self, value: u16)
[src]
Set the identifier field (for echo request and reply packets).
Panics
This function may panic if this packet is not an echo request or reply packet.
pub fn set_echo_seq_no(&mut self, value: u16)
[src]
Set the sequence number field (for echo request and reply packets).
Panics
This function may panic if this packet is not an echo request or reply packet.
pub fn fill_checksum(&mut self)
[src]
Compute and fill in the header checksum.
