Implementations

impl Packet

pub fn from_bytes(bytes: &[u8]) -> Result<Self, PacketError>

Parse a packet from a byte array

let packet = &[0u8, 1, 67, 68, 69, 0, 0x6f, 0x63, 0x74, 0x65, 0x74, 0];
let packet = Packet::from_bytes(packet).unwrap();
assert_eq!(packet, Packet::RRQ {
   filename: "CDE".to_string(),
   mode: Mode::Octet,
});

pub fn to_bytes(self) -> Vec<u8>

Serialize a packet into a byte array

let packet = Packet::RRQ {
  filename: "CDE".to_string(),
  mode: Mode::Octet,
};
let packet = packet.to_bytes();
assert_eq!(packet, &[0u8, 1, 67, 68, 69, 0, 0x6f, 0x63, 0x74, 0x65, 0x74, 0]);

Trait Implementations

impl Clone for Packet

fn clone(&self) -> Packet

Returns a duplicate 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

Formats the value using the given formatter.

impl PartialEq for Packet

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

Tests for self and other values to be equal, and is used by ==.

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

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