# Trait core::fmt::Display 1.0.0[−][src]

    pub trait Display {
        fn fmt(&self, f: &mut Formatter<'_>) -> Result;
    }

Format trait for an empty format, `{}`.

`Display` is similar to `Debug`, but `Display` is for user-facing output, and so cannot be derived.

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

# Examples

Implementing `Display` on a type:

    use std::fmt;

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

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

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

    assert_eq!(format!("The origin is: {}", origin), "The origin is: (0, 0)");

Run

## Required methods

### `fn fmt(&self, f: &mut Formatter<'_>) -> Result`[src]

Formats the value using the given formatter.

# Examples

    use std::fmt;

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

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

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