Crate durian_proc_macros

Procedural macros for the durian crate

Contains macros for easily annotating structs as Packets and automatically implementing PacketBuilders. The only requirement is the struct must be de/serializable, meaning all nested fields also need to be de/serializable.

#[bincode_packet] will de/serialize your Packet using bincode and applies necessary derive macros automatically for you.

use durian::bincode_packet;

// Automatically implements Packet, and generates a PositionPacketBuilder that implements
// PacketBuilder.  You can also add other macros such as derive macros so long s they don't
// conflict with what #[bincode_packet] adds (See bincode_packet documentation).
#[bincode_packet]
#[derive(Debug)]
struct Position {
    x: i32,
    y: i32
}

// Works for Unit (empty) structs as well
#[bincode_packet]
struct Ack;

You can also use the derive macros (BinPacket and UnitPacket) manually:

use durian::serde::{Deserialize, Serialize};
use durian::{BinPacket, UnitPacket};

#[derive(Serialize, Deserialize, BinPacket)]
#[serde(crate = "durian::serde")]
struct Position { x: i32, y: i32 }

#[derive(UnitPacket)]
struct Ack;

Attribute Macros

• bincode_packet
  Macros for easy creation of Packets and PacketBuilders

Derive Macros

• BinPacket
  derive macro to automatically implement Packet and PacketBuilder for a struct.
• DerefPacketManager
  Convenience derive macro that implements [Deref] and [DerefMut] for a struct that contains a manager: PacketManager field.
• ErrorOnlyMessage
  Implements a new() function for a struct that contains only a message: String field
• UnitPacket
  Same as BinPacket but for empty or Unit structs
