Struct GreSlice 

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

Available on crate feature extractors only.

GRE (Generic Routing Encapsulation) header slice.

RFC 2784 fixed 4-byte header; RFC 2890 + variants add optional Checksum, Key, Sequence fields conditionally.

Implementations

impl<'a> GreSlice<'a>

pub fn has_checksum(&self) -> bool

Checksum-present bit.

pub fn has_key(&self) -> bool

Key-present bit.

pub fn has_sequence(&self) -> bool

Sequence-number-present bit.

pub fn protocol_type(&self) -> u16

Protocol type (EtherType of the encapsulated payload).

pub fn header_len(&self) -> usize

Compute the header length in bytes given the present optional fields. 4-byte base + 4 each for checksum, key, sequence.

pub fn header(&self) -> &'a [u8]

pub fn bytes(&self) -> &'a [u8]

pub fn kind(&self) -> LayerKind
