pub struct UdpPacket<T: AsRef<[u8]>> { /* private fields */ }
Expand description
A read/write wrapper around an User Datagram Protocol packet buffer.
Implementations§
source§impl<T: AsRef<[u8]>> Packet<T>
impl<T: AsRef<[u8]>> Packet<T>
sourcepub const fn new_unchecked(buffer: T) -> Packet<T>
pub const fn new_unchecked(buffer: T) -> Packet<T>
Imbue a raw octet buffer with UDP packet structure.
sourcepub fn new_checked(buffer: T) -> Result<Packet<T>>
pub fn new_checked(buffer: T) -> Result<Packet<T>>
Shorthand for a combination of new_unchecked and check_len.
sourcepub fn check_len(&self) -> Result<()>
pub fn check_len(&self) -> Result<()>
Ensure that no accessor method will panic if called.
Returns Err(Error)
if the buffer is too short.
Returns Err(Error)
if the length field has a value smaller
than the header length.
The result of this check is invalidated by calling set_len.
sourcepub fn into_inner(self) -> T
pub fn into_inner(self) -> T
Consume the packet, returning the underlying buffer.
source§impl<T: AsRef<[u8]> + AsMut<[u8]>> Packet<T>
impl<T: AsRef<[u8]> + AsMut<[u8]>> Packet<T>
sourcepub fn set_src_port(&mut self, value: u16)
pub fn set_src_port(&mut self, value: u16)
Set the source port field.
sourcepub fn set_dst_port(&mut self, value: u16)
pub fn set_dst_port(&mut self, value: u16)
Set the destination port field.
sourcepub fn set_checksum(&mut self, value: u16)
pub fn set_checksum(&mut self, value: u16)
Set the checksum field.
sourcepub fn fill_checksum(&mut self, src_addr: &IpAddress, dst_addr: &IpAddress)
pub 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.
sourcepub fn payload_mut(&mut self) -> &mut [u8] ⓘ
pub fn payload_mut(&mut self) -> &mut [u8] ⓘ
Return a mutable pointer to the payload.
