# Trait std::fmt::Debug 1.0.0[−][src]

    #[lang = "debug_trait"]
    pub trait Debug {
        fn fmt(&self, f: &mut Formatter) -> Result<(), Error>;
    }

`?` formatting.

`Debug` should format the output in a programmer-facing, debugging context.

Generally speaking, you should just `derive` a `Debug` implementation.

When used with the alternate format specifier `#?`, the output is pretty-printed.

For more information on formatters, see the module-level documentation.

This trait can be used with `#[derive]` if all fields implement `Debug`. When `derive`d for structs, it will use the name of the `struct`, then `{`, then a comma-separated list of each field's name and `Debug` value, then `}`. For `enum`s, it will use the name of the variant and, if applicable, `(`, then the `Debug` values of the fields, then `)`.

# Examples

Deriving an implementation:

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

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

    println!("The origin is: {:?}", origin);Run

Manually implementing:

    use std::fmt;

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

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

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

    println!("The origin is: {:?}", origin);Run

This outputs:

    The origin is: Point { x: 0, y: 0 }

There are a number of `debug_*` methods on `Formatter` to help you with manual implementations, such as `debug_struct`.

`Debug` implementations using either `derive` or the debug builder API on `Formatter` support pretty printing using the alternate flag: `{:#?}`.

Pretty printing with `#?`:

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

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

    println!("The origin is: {:#?}", origin);Run

This outputs:

    The origin is: Point {
        x: 0,
        y: 0
    }

## Required Methods

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

Formats the value using the given formatter.

# Examples

    use std::fmt;

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

    impl fmt::Debug for Position {
        fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
            write!(f, "({:?}, {:?})", self.longitude, self.latitude)
        }
    }

    assert_eq!("(1.987, 2.983)".to_owned(),
               format!("{:?}", Position { longitude: 1.987, latitude: 2.983, }));Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
