Implementations

impl Packet

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

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.

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.

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

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

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

Trait Implementations

impl Clone for Packet

fn clone(&self) -> Packet

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Packet

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Packet

fn default() -> Packet

Returns the “default value” for a type.

impl PartialEq<Packet> for Packet

fn eq(&self, other: &Packet) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
