Implementations§

source§

impl Packet

source

pub fn new(buffer: [u8; 1232], meta: Meta) -> Packet

source

pub fn data<I>(&self, index: I) -> Option<&<I as SliceIndex<[u8]>>::Output>
where I: SliceIndex<[u8]>,

Returns an immutable reference to the underlying buffer up to packet.meta.size. The rest of the buffer is not valid to read from. packet.data(..) returns packet.buffer.get(..packet.meta.size). Returns None if the index is invalid or if the packet is already marked as discard.

source

pub fn buffer_mut(&mut self) -> &mut [u8]

Returns a mutable reference to the entirety of the underlying buffer to write into. The caller is responsible for updating Packet.meta.size after writing to the buffer.

source

pub fn meta(&self) -> &Meta

source

pub fn meta_mut(&mut self) -> &mut Meta

source

pub fn from_data<T>( dest: Option<&SocketAddr>, data: T, ) -> Result<Packet, Box<ErrorKind>>
where T: Serialize,

source

pub fn populate_packet<T>( &mut self, dest: Option<&SocketAddr>, data: &T, ) -> Result<(), Box<ErrorKind>>
where T: Serialize,

source

pub fn deserialize_slice<T, I>(&self, index: I) -> Result<T, Box<ErrorKind>>
where T: DeserializeOwned, I: SliceIndex<[u8], Output = [u8]>,
