# anony
Provides various constructs for anonymous types.
## Macros
* [`struct!`]: Creates an instance of an anonymous struct.
```rust
use anony::r#struct;
let items = vec![1, 3, 5];
let x = r#struct! {
name: "anony".to_owned(),
// Move the `items` variable into the struct
items,
};
assert_eq!(x.name, "anony");
assert_eq!(x.items, [1, 3, 5]);
```
* [`tuple!`]: Creates an instance of an anonymous tuple.
```rust
use anony::tuple;
let items = vec![1, 3, 5];
let x = tuple!("anony".to_owned(), items);
assert_eq!(x.0, "anony");
assert_eq!(x.1, [1, 3, 5]);
```
* [`combine_futures!`] and [`combine_futures_cyclic!`]:
General-purpose future concurrency combinators. Requires the `future` feature.
```rust
let mut s = String::new();
let fut = combine_futures! {
let ten = async { 10 } => continue {
s.write_fmt(format_args!("{ten}"));
ten
}
let zero = async { "0" } => continue s.push_str(zero),
};
assert_eq!(fut.await, (10, ()));
assert_eq!(s, "100");
```
```rust
let mut x = 2;
let fut = combine_futures_cyclic! {
move
match async { Some(1) } {
Some(x) if x % 2 == 0 => continue,
_ => break {
x += 1;
x
}
}
continue async {},
|_, _| -1
};
assert_eq!(fut.await, 3);
assert_eq!(x, 2);
```
## Example Macro Expansions

## Features
* `serde`: Derives [`Serialize`] for anonymous structs and tuples.
The [serde] crate must be included in your dependencies.
* `future`: Enables [`Future`] anonymous types, such as [`combine_futures!`].
## Nightly
Add this to your dependencies:
```toml
anony = { git = "https://github.com/discreaminant2809/anony.git", branch = "nightly" }
