【Serde】格式转换

环境

• Time 2021-12-07
• Rust 1.57.0
• serde 1.0.130
• serde_json 1.0.72

概念

参考：https://serde.rs/transcode.html

示例

main.rs

use std::io;

fn main() {
    // A JSON input with plenty of whitespace.
    let input = r#"
      {
        "a boolean": true,
        "an array": [3, 2, 1]
      }
    "#;

    // A JSON deserializer. You can use any Serde Deserializer here.
    let mut deserializer = serde_json::Deserializer::from_str(input);

    // A compacted JSON serializer. You can use any Serde Serializer here.
    let mut serializer = serde_json::Serializer::new(io::stdout());

    // Prints `{"a boolean":true,"an array":[3,2,1]}` to stdout.
    // This line works with any self-describing Deserializer and any Serializer.
    serde_transcode::transcode(&mut deserializer, &mut serializer).unwrap();
}

Cargo.toml

[package]
edition = "2021"
name = "game"
version = "0.1.0"

[dependencies]

serde = {version = "1", features = ["derive"]}
serde-transcode = "1"
serde_json = "1"

总结

使用 serde 实现了 JSON 格式的紧凑功能。
