Impl Display Macro

The implementation of trait Display.

See more macros: docs, repository.

Examples:

Struct

#[derive(Display)]
struct Test;
assert_eq!(Test {}.to_string(), "Test");

#[derive(Display)]
#[display(fmt = "Hello, {name}!")]
struct Hello {
    pub name: &'static str,
    pub age: u8,
}

assert_eq!(
    Hello {
        name: "User",
        age: 24
    }
    .to_string(),
    "Hello, User!"
);

Enum

#[derive(Display)]
#[display(rename = "lowercase")]
enum Animals {
    Dog,

    Cat(&'static str'),

    #[display(fmt = "It's {0} tiger")]
    Tiger(&'static str, u8),

    #[display(fmt = "It's {name} bird")]
    Bird {
        name: &'static str,
        age: u8,
    },
}

assert_eq!(Animals::Dog.to_string(), "dog");
assert_eq!(Animals::Cat("Tom").to_string(), "Tom");
assert_eq!(Animals::Tiger("Simba", 1).to_string(), "It's Simba tiger");
assert_eq!(
    Animals::Bird {
        name: "Kesha",
        age: 1,
    }
    .to_string(),
    "It's Kesha bird"
);
