Implementations
impl<'a> GrePacket<'a>
[src]
impl<'a> GrePacket<'a>
[src]pub fn new<'p>(packet: &'p [u8]) -> Option<GrePacket<'p>>
[src]
pub fn new<'p>(packet: &'p [u8]) -> Option<GrePacket<'p>>
[src]Constructs a new #name. If the provided buffer is less than the minimum required packet size, this will return None.
pub fn owned(packet: Vec<u8>) -> Option<GrePacket<'static>>
[src]
pub fn owned(packet: Vec<u8>) -> Option<GrePacket<'static>>
[src]Constructs a new #name. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the #name will own its own data and the underlying buffer will be dropped when the #name is.

[src]
pub fn get_strict_source_route(&self) -> u1
[src]Get the strict_source_route field. This field is always stored big-endian within the struct, but this accessor returns host order.
pub fn get_recursion_control(&self) -> u3
[src]
pub fn get_recursion_control(&self) -> u3
[src]Get the recursion_control field. This field is always stored big-endian within the struct, but this accessor returns host order.
pub fn get_zero_flags(&self) -> u5
[src]
pub fn get_zero_flags(&self) -> u5
[src]Get the zero_flags field. This field is always stored big-endian within the struct, but this accessor returns host order.
pub fn get_version(&self) -> u3
[src]
pub fn get_version(&self) -> u3
[src]Get the version field. This field is always stored big-endian within the struct, but this accessor returns host order.
pub fn get_protocol_type(&self) -> u16be
[src]
pub fn get_protocol_type(&self) -> u16be
[src]Get the protocol_type field. This field is always stored big-endian within the struct, but this accessor returns host order.
