Implementations§
Source§impl<'a> MutableGrePacket<'a>
impl<'a> MutableGrePacket<'a>
Sourcepub fn new<'p>(packet: &'p mut [u8]) -> Option<MutableGrePacket<'p>>
pub fn new<'p>(packet: &'p mut [u8]) -> Option<MutableGrePacket<'p>>
Constructs a new #name. If the provided buffer is less than the minimum required packet size, this will return None.
Sourcepub fn owned(packet: Vec<u8>) -> Option<MutableGrePacket<'static>>
pub fn owned(packet: Vec<u8>) -> Option<MutableGrePacket<'static>>
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.
Sourcepub fn to_immutable<'p>(&'p self) -> GrePacket<'p>
pub fn to_immutable<'p>(&'p self) -> GrePacket<'p>
Maps from a #name to a #imm_name
Sourcepub fn consume_to_immutable(self) -> GrePacket<'a>
pub fn consume_to_immutable(self) -> GrePacket<'a>
Maps from a #name to a #imm_name while consuming the source
Sourcepub const fn minimum_packet_size() -> usize
pub const fn minimum_packet_size() -> usize
The minimum size (in bytes) a packet of this type can be. It’s based on the total size of the fixed-size fields.

pub fn packet_size(_packet: &Gre) -> usize
The size (in bytes) of a #base_name instance when converted into a byte-array
