indented

使用缩进来格式化数据

[dependencies]
indented = "0.1.0"

extern crate indented;

use indented::indented;

fn main() {
    let x = "statement";
    let y = format!("nested {{\n{};\n}}", indented(&x));
    println!("block {{\n{};\n{}\n}}", indented(&x), indented(&y));
}

输出

block {
    statement;
    nested {
        statement;
    }
}
