Serde CBOR

本crate实现了RFC 7049中的 Concise Binary Object Representation。它基于Serde，Rust的通用序列化框架。CBOR为JSON数据模型的超集提供了一个小型且解析速度非常快的二进制编码。

用法

Serde CBOR支持Rust 1.40及以上版本。将以下内容添加到您的Cargo.toml

[dependencies]
serde_cbor = "0.11.1"

存储和加载Rust类型非常容易，只需对程序代码进行最小修改。

use serde_derive::{Deserialize, Serialize};
use std::error::Error;
use std::fs::File;

// Types annotated with `Serialize` can be stored as CBOR.
// To be able to load them again add `Deserialize`.
#[derive(Debug, Serialize, Deserialize)]
struct Mascot {
    name: String,
    species: String,
    year_of_birth: u32,
}

fn main() -> Result<(), Box<dyn Error>> {
    let ferris = Mascot {
        name: "Ferris".to_owned(),
        species: "crab".to_owned(),
        year_of_birth: 2015,
    };

    let ferris_file = File::create("examples/ferris.cbor")?;
    // Write Ferris to the given file.
    // Instead of a file you can use any type that implements `io::Write`
    // like a HTTP body, database connection etc.
    serde_cbor::to_writer(ferris_file, &ferris)?;

    let tux_file = File::open("examples/tux.cbor")?;
    // Load Tux from a file.
    // Serde CBOR performs roundtrip serialization meaning that
    // the data will not change in any way.
    let tux: Mascot = serde_cbor::from_reader(tux_file)?;

    println!("{:?}", tux);
    // prints: Mascot { name: "Tux", species: "penguin", year_of_birth: 1996 }

    Ok(())
}

有很多选项可供自定义格式。要操作无类型的CBOR值，请查看Value类型。
