Struct pnet_packet::gre::GrePacket [−][src]
pub struct GrePacket<'p> { /* fields omitted */ }Expand description
A structure enabling manipulation of on the wire packets
Implementations
Constructs a new GrePacket. If the provided buffer is less than the minimum required packet size, this will return None.
Constructs a new GrePacket. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the GrePacket will own its own data and the underlying buffer will be dropped when the GrePacket is.
Maps from a GrePacket to a GrePacket
Maps from a GrePacket to a GrePacket while consuming the source
The minimum size (in bytes) a packet of this type can be. It’s based on the total size of the fixed-size fields.
The size (in bytes) of a Gre instance when converted into a byte-array
Get the checksum_present field.
Get the routing_present field.
Get the key_present field.
Get the sequence_present field.
Get the strict_source_route field.
Get the recursion_control field.
Get the zero_flags field.
Get the version field.
Get the protocol_type field. This field is always stored big-endian within the struct, but this accessor returns host order.
Get the raw &u8 value of the checksum field, without copying
Get the value of the checksum field (copies contents)
