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 MutableGrePacket. 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 MutableGrePacket. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the MutableGrePacket will own its own data and the underlying buffer will be dropped when the MutableGrePacket is.
sourcepub fn to_immutable<'p>(&'p self) -> GrePacket<'p>
pub fn to_immutable<'p>(&'p self) -> GrePacket<'p>
Maps from a MutableGrePacket to a GrePacket
sourcepub fn consume_to_immutable(self) -> GrePacket<'a>
pub fn consume_to_immutable(self) -> GrePacket<'a>
Maps from a MutableGrePacket to a GrePacket 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.
