# Trait ethcore_util::standard::fmt::Display 1.0.0 [−] [src]

    pub trait Display {
        fn fmt(&self, &mut Formatter) -> Result<(), Error>;
    }

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 };

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

## Required Methods

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

Formats the value using the given formatter.

## 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`)
