Struct MutableUdpPacket 

pub struct MutableUdpPacket<'a> { /* private fields */ }

Represents a mutable UDP packet.

Implementations

impl<'a> MutableUdpPacket<'a>

pub fn new_unchecked(buffer: &'a mut [u8]) -> Self

Create a new packet without validating length fields.

pub fn checksum_mode(&self) -> ChecksumMode

Returns the checksum recalculation mode.

pub fn set_checksum_mode(&mut self, mode: ChecksumMode)

Sets the checksum recalculation mode.

pub fn enable_auto_checksum(&mut self)

Enables automatic checksum recalculation when tracked fields change.

pub fn disable_auto_checksum(&mut self)

Disables automatic checksum recalculation.

pub fn is_checksum_dirty(&self) -> bool

Returns true if the checksum needs to be recomputed.

pub fn mark_checksum_dirty(&mut self)

Marks the checksum as stale and recomputes it when automatic mode is enabled.

pub fn set_checksum_context(&mut self, context: TransportChecksumContext)

Defines the pseudo-header context used when recomputing the checksum.

pub fn set_ipv4_checksum_context( &mut self, source: Ipv4Addr, destination: Ipv4Addr, )

Sets an IPv4 pseudo-header context used for checksum recomputation.

pub fn set_ipv6_checksum_context( &mut self, source: Ipv6Addr, destination: Ipv6Addr, )

Sets an IPv6 pseudo-header context used for checksum recomputation.

pub fn clear_checksum_context(&mut self)

Clears the configured checksum pseudo-header context.

pub fn checksum_context(&self) -> Option<TransportChecksumContext>

Provides access to the configured checksum pseudo-header context.

pub fn recompute_checksum(&mut self) -> Option<u16>

Recomputes the UDP checksum if a pseudo-header context is available.

pub fn total_len(&self) -> usize

Returns the total length derived from the UDP length field.

pub fn payload_len(&self) -> usize

Returns the payload length.

pub fn get_source(&self) -> u16

pub fn set_source(&mut self, port: u16)

pub fn get_destination(&self) -> u16

pub fn set_destination(&mut self, port: u16)

pub fn get_length(&self) -> u16

pub fn set_length(&mut self, length: u16)

pub fn get_checksum(&self) -> u16

pub fn set_checksum(&mut self, checksum: u16)
