通常，宏将自动通过调用 Code::from 将输入转换为 Code。

use codize::{cblock, clist, cconcat};

let code = cconcat![
    "",
    "/// This block is auto-generated",
    "",
    cblock!("fn main() {", [
        cblock!("println!(", [
            clist!("," => [r#""{}, {}!""#, r#""Hello""#, r#""world!""#])
        ], ");")
    ], "}"),
];

let expected = r#"
/// This block is auto-generated

fn main() {
    println!(
        "{}, {}!",
        "Hello",
        "world!",
    );
}"#;

assert_eq!(expected, code.to_string());

Format 示例

您可以使用 FormatCode 特性和 Format 结构体来更改全局格式化选项

use codize::{cblock, Format, FormatCode};
let code = cblock!("fn main() {", ["println!(\"Hello, world!\");"], "}");

let indent_2 = 
r#"fn main() {
  println!("Hello, world!");
}"#;
assert_eq!(indent_2, code.format_with(&Format::indent(2)));

let indent_tab =
"fn main() {
\tprintln!(\"Hello, world!\");
}";
assert_eq!(indent_tab, code.format_with(&Format::indent_tab()));
