anon

anon!{} is a Rust macro which create anonymous structs, like C# anonymous types.

Usage

Add this to your Cargo.toml:

toml [dependencies] anon = { git = "https://github.com/ktakeda/anon" }

and this to your crate root:

```rust

[macro_use(anon)]

extern crate anon; ```

Examples

```rust

[macro_use(anon)]

extern crate anon;

[allow(noncamelcase_types)]

fn main() { let a = anon! { a: 10, b: 20 }; asserteq!(10, a.a); asserteq!(20, a.b); } ```

Anon can be used in closure:

```rust

[macro_use(anon)]

extern crate anon;

[allow(noncamelcase_types)]

fn main() { let y: Vec<_> = vec![1,2].intoiter().map(|x| { anon! { a: x, b: x*x } // create anonymous struct }).collect(); asserteq!(1, y[0].a); asserteq!(2, y[1].a); asserteq!(1, y[0].b); assert_eq!(4, y[1].b); } ```
