pub type Result = Result<(), Error>;

The type returned by formatter methods.

Examples

use std::fmt;

#[derive(Debug)]
struct Triangle {
    a: f32,
    b: f32,
    c: f32
}

impl fmt::Display for Triangle {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        write!(f, "({}, {}, {})", self.a, self.b, self.c)
    }
}

let pythagorean_triple = Triangle { a: 3.0, b: 4.0, c: 5.0 };

assert_eq!(format!("{pythagorean_triple}"), "(3, 4, 5)");
