Trait Packet 

pub trait Packet<'a> {
    // Required methods
    fn mbuf(&self) -> &Mbuf;
    fn header_len(&self) -> usize;
    fn next_header_offset(&self) -> usize;
    fn next_header(&self) -> Option<usize>;
    fn parse_from(outer: &'a impl Packet<'a>) -> Result<Self, PacketParseError>
       where Self: Sized;

    // Provided method
    fn parse_to<T: Packet<'a>>(&'a self) -> Result<T, PacketParseError>
       where Self: Sized { ... }
}

Represents a single packet.

Required Methods

fn mbuf(&self) -> &Mbuf

Reference to the underlying packet buffer.

fn header_len(&self) -> usize

Offset from the beginning of the header to the start of the payload.

fn next_header_offset(&self) -> usize

Offset from the beginning of the packet buffer to the start of the payload.

fn next_header(&self) -> Option<usize>

Next level IANA protocol number.

fn parse_from(outer: &'a impl Packet<'a>) -> Result<Self, PacketParseError>

where Self: Sized,

Parses a Packet from the outer encapsulating Packet’s payload.

Provided Methods

fn parse_to<T: Packet<'a>>(&'a self) -> Result<T, PacketParseError>

where Self: Sized,

Parses the Packet’s payload as a new Packet of type T.

Returns the concrete PacketParseError if parsing fails.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
