A high-level representation of an Internet Control Message Protocol version 4 packet header.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl<'a> Repr<'a>

pub fn parse<T>( packet: &Packet<&'a T>, checksum_caps: &ChecksumCapabilities, ) -> Result<Repr<'a>>

where T: AsRef<[u8]> + ?Sized,

Parse an Internet Control Message Protocol version 4 packet and return a high-level representation.

pub const fn buffer_len(&self) -> usize

Return the length of a packet that will be emitted from this high-level representation.

pub fn emit<T>( &self, packet: &mut Packet<&mut T>, checksum_caps: &ChecksumCapabilities, )

where T: AsRef<[u8]> + AsMut<[u8]> + ?Sized,

Emit a high-level representation into an Internet Control Message Protocol version 4 packet.

Trait Implementations

impl<'a> Clone for Repr<'a>

fn clone(&self) -> Repr<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for Repr<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Display for Repr<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> From<Repr<'a>> for Repr<'a>

fn from(s: Repr<'a>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for Repr<'a>

fn eq(&self, other: &Repr<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
