Provides various anonymous type constructs

Macros

• struct!: creates an instance of an anonymous struct.

use anony::r#struct;

let items = vec![1, 3, 5];

let x = r#struct! {
    color: "Red".to_owned(),
    // move the `items` variable to the struct
    items
};

assert_eq!(x.color, "Red");
assert_eq!(x.items, [1, 3, 5]);

• tuple!: creates an instance of an anonymous tuple.

use anony::tuple;

let items = vec![1, 3, 5];

let x = tuple!("Red".to_owned(), items);

assert_eq!(x.0, "Red");
assert_eq!(x.1, [1, 3, 5]);

• join! and join_cyclic!: join multiple futures. Require future feature.

use anony::join;

assert_eq!(join!(async { 2 }, async { "123" }).await, (2, "123"));

• try_join! and try_join_cyclic!: join multiple futures and short-circuit on "break" value. Require future feature.

use anony::try_join;

assert_eq!(try_join!(async { Some(2) }, async { Some("123") }).await, Some((2, "123")));
assert_eq!(try_join!(async { Some(2) }, async { None::<i32> }).await, None);

Features

• serde: derives Serialize for anonymous structs and tuples. serde crate must exist in your crate.
• future: enables Future anonymous types, such as join!.
