Lib3d6

这是我的Rust实用程序库，有很多类似的库，几乎在所有方面都更优秀，但这是属于我的。

目前它是一个玩具项目，因为我正在重新学习这门语言。

F-字符串打印

Python打印很酷，在Rust中实现它相当简单。

警告：当前实现是WIP，它工作，但肯定有错误，效率低下，有些难看。

// Importing is kind of ugly, looking for help making it better
// `*` import leads to ambiguity, and I can't get an import macro working
use lib3d6::{format, print, println};

let v1 = ("arga", "barga", 33);
let v2 = 121421;
let v3: f32 = 32.12;
let v4: &str = "Ahhha";
let v5 = ["1", "2", "three"];
let v6 = "have".to_owned();
let v7 = Some("tea");

assert_eq!(
    // Overrides format to support f-string
    format!(f"This is {v7}"),
    
    // Ugly old format still works
    format!("This is {:?}", v7)
);

// Same thing happens with print and println
println!(f"{v5} {v6} {v7}");
print!(f"It can work with any object of a type that implements the Debug trait, such as this tuple: {v1}\n");
print!(f"But also with primitives like v3 ({v3}), and it handles duplicates: {v4}, {v4}, {v4}");
println!("\nBut as always, {} still {:?}", "the old way of doing things", "works");
