Struct MutableIcmpPacket 

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

Represents a mutable ICMP packet.

Implementations

impl<'a> MutableIcmpPacket<'a>

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

Create a mutable ICMP packet without performing validation.

pub fn checksum_mode(&self) -> ChecksumMode

Returns the checksum recalculation mode.

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

Sets how checksum updates should be handled.

pub fn enable_auto_checksum(&mut self)

Enables automatic checksum recomputation.

pub fn disable_auto_checksum(&mut self)

Disables automatic checksum recomputation.

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 dirty and recomputes it when automatic mode is enabled.

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

Recomputes the checksum for the current packet contents.

pub fn get_type(&self) -> IcmpType

Returns the current ICMP type field.

pub fn set_type(&mut self, icmp_type: IcmpType)

Sets the ICMP type field and marks the checksum as dirty.

pub fn get_code(&self) -> IcmpCode

Returns the current ICMP code field.

pub fn set_code(&mut self, icmp_code: IcmpCode)

Sets the ICMP code field and marks the checksum as dirty.

pub fn get_checksum(&self) -> u16

Returns the serialized checksum value.

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

Sets the serialized checksum value and clears the dirty flag.
