}
Expand description

? 格式。

Debug 应该在面向程序员的调试上下文中格式化输出。

一般来说,您应该只将 deriveDebug 实现。

当与备用格式说明符 #? 一起使用时,输出将被漂亮地打印。

有关格式化程序的更多信息,请参见 模块级文档

如果所有字段都实现 Debug,则此 trait 可以与 #[derive] 一起使用。当为结构体 derived' 时,它将使用 struct的名称,然后是{,然后是每个字段名称和 Debug值的逗号分隔列表,然后是}。 对于 enum,它将使用变体的名称,如果适用,将使用 (,然后是字段的 Debug值,然后是)`。

Stability

派生的 Debug 格式不稳定,因此 future Rust 版本可能会更改。此外,标准库 (stdcorealloc 等) 提供的类型的 Debug 实现并不稳定,并且也可能随着 future Rust 版本而改变。

Examples

派生实现:

#[derive(Debug)]
struct Point {
    x: i32,
    y: i32,
}

let origin = Point { x: 0, y: 0 };

assert_eq!(format!("The origin is: {origin:?}"), "The origin is: Point { x: 0, y: 0 }");
Run

手动实现:

use std::fmt;

struct Point {
    x: i32,
    y: i32,
}

impl fmt::Debug for Point {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        f.debug_struct("Point")
         .field("x", &self.x)
         .field("y", &self.y)
         .finish()
    }
}

let origin = Point { x: 0, y: 0 };

assert_eq!(format!("The origin is: {origin:?}"), "The origin is: Point { x: 0, y: 0 }");
Run

Formatter 结构体上有许多辅助方法可以帮助您实现手动实现,例如 debug_struct

不希望使用 Formatter trait 提供的标准调试表示套件 (debug_structdebug_tupledebug_listdebug_setdebug_map) 的类型可以通过手动向 Formatter 写入任意表示来完成完全自定义的操作。

impl fmt::Debug for Point {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        write!(f, "Point [{} {}]", self.x, self.y)
    }
}
Run

使用 deriveFormatter 上的调试构建器 API 的 Debug 实现支持使用备用标志 {:#?} 的漂亮打印。

使用 #? 进行漂亮的打印:

#[derive(Debug)]
struct Point {
    x: i32,
    y: i32,
}

let origin = Point { x: 0, y: 0 };

assert_eq!(format!("The origin is: {origin:#?}"),
"The origin is: Point {
    x: 0,
    y: 0,
}");
Run

Required Methods§

source

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

使用给定的格式化程序格式化该值。

Examples
use std::fmt;

struct Position {
    longitude: f32,
    latitude: f32,
}

impl fmt::Debug for Position {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        f.debug_tuple("")
         .field(&self.longitude)
         .field(&self.latitude)
         .finish()
    }
}

let position = Position { longitude: 1.987, latitude: 2.983 };
assert_eq!(format!("{position:?}"), "(1.987, 2.983)");

assert_eq!(format!("{position:#?}"), "(
    1.987,
    2.983,
)");
Run
