结构体（反）序列化

该包提供了一个非常简单的结构体（反）序列化方法。主要目的是帮助处理数据包。

功能

• derive(StructDeser)
• 处理字节序
• 关联常量
• 无std

用法

extern crate struct_deser;
#[macro_use]
extern crate struct_deser_derive;

// derive traits
#[derive(StructDeser, Debug, Eq, PartialEq)]
struct Packet {
    // mark as big endian
    // this is mandatory because u16 has multiple bytes
    #[be]
    version: u16,
    // u8 goes without endianess attribute
    ttl: u8,
    // mark as little endian
    #[le]
    chksum: u32,
}

fn main() {
    use struct_deser::{SerializedByteLen,FromBytes,IntoBytes};

    let packet0 = Packet {
        version: 1,
        ttl: 42,
        chksum: 47,
    };

    let mut bytes = [0; Packet::BYTE_LEN];
    packet0.into_bytes(&mut bytes);
    let packet1 = Packet::from_bytes(&bytes);

    assert_eq!(packet0, packet1);
}
