Struct packet_formats::ipv6::Ipv6PacketRaw

pub struct Ipv6PacketRaw<B> { /* private fields */ }

A partially parsed and not yet validated IPv6 packet.

Ipv6PacketRaw provides minimal parsing of an IPv6 packet, namely it only requires that the fixed header part ([HeaderPrefix]) be retrieved, all the other parts of the packet may be missing when attempting to create it.

Ipv6Packet provides a [FromRaw] implementation that can be used to validate an Ipv6PacketRaw.

Implementations

impl<B: ByteSlice> Ipv6PacketRaw<B>

pub fn body_proto( &self ) -> Result<(MaybeParsed<&[u8], &[u8]>, Ipv6Proto), ExtHdrParseError>

Returns the body and upper-layer Protocol Number.

If extension headers failed to parse, body_proto returns Err(ExtHdrParseError). Extension headers must be parsed in order to find the bounds of the upper-layer payload and to find that last extension header’s Next Header field, which is the Protocol Number of the upper-layer payload.

The returned body will be [MaybeParsed::Complete] if all the body bytes were consumed (as stated by the header’s payload length value) or [MaybeParsed::Incomplete] containing the bytes that were present otherwise.

pub fn body(&self) -> Result<MaybeParsed<&[u8], &[u8]>, ExtHdrParseError>

Returns the body.

If extension headers failed to parse, body returns Err(ExtHdrParseError). Extension headers must be parsed in order to find the bounds of the upper-layer payload.

The returned body will be [MaybeParsed::Complete] if all the body bytes were consumed (as stated by the header’s payload length value) or [MaybeParsed::Incomplete] containing the bytes that were present otherwise.

pub fn proto(&self) -> Result<Ipv6Proto, ExtHdrParseError>

Returns the upper-layer Protocol Number.

If extension headers failed to parse, body_proto returns Err(ExtHdrParseError). Extension headers must be parsed in order to find the last extension header’s Next Header field, which is the Protocol Number of the upper-layer payload.
