所以我目前难以struct通过将Yaml文件加载到堆内存来初始化:

extern crate yaml_rust;

use std::io::prelude::*;
use std::fs;
use yaml_rust::{Yaml, YamlLoader};

struct Petrovich {
    middlename: Yaml,
    firstname: Yaml,
    lastname: Yaml
}

impl  Petrovich {

    fn new() -> Petrovich {

        // Open Rules File (Panics on error)
        let mut f = fs::File::open("./src/rules.yml").unwrap();
        // Create String Buffer and Read to it
        let mut buffer = String::new();
        f.read_to_string(&mut buffer).unwrap();
        // Pass Buffer to Yaml and unwrap
        let rules: &Yaml = &YamlLoader::load_from_str(&buffer).unwrap()[0];

        // Return Petrovich with preloaded rules
        Petrovich { …

使用println!按预期工作时:

println!("??????!"); // ??????!

但是使用调试格式:

println!("{:?}", "??????!"); // "\u{41f}\u{440}\u{438}\u{432}\u{435}\u{442}!"

使用assert!:

assert!("??????!" != "??????!") // 'assertion failed: "\u{41f}\u{440}\u{438}\u{432}\u{435}\u{442}!" != "\u{41f}\u{440}\u{438}\u{432}\u{435}\u{442}!"

有没有办法以assert!调试格式正确打印？
