rand_derive

#[derive(Rand)] functionality enabling sampling of random instances.

This crate is deprecated as of rand 0.5 since the Rand trait has been deprecated and since it appears to have very little use.

This crate has been updated to work with Rand 0.5, however note that it now implements Distribution<Self> for Standard instead of Rand.

Usage

Add this to your Cargo.toml:

toml [dependencies] rand = "0.5" rand_derive = "0.5"

and this to your crate root:

```rust extern crate rand;

[macro_use]

extern crate rand_derive; ```

Examples

#[derive(Rand)] can be used on any struct or enum where all fields/variants implement rand::Rand.

```rust

[derive(Debug, Rand)]

struct Foo { x: u16, y: Option, }

[derive(Debug, Rand)]

enum Bar { X{x: u8, y: isize}, Y([bool; 4]), Z, } `` Now you can call theRng::gen()` function on your custom types.

```rust use rand::Rng;

let mut rng = rand::thread_rng();

println!("{:?}", rng.gen::()); println!("{:?}", rng.gen::()); ```
