with-thread-local

=================

A micro crate that simplifies a bit the use of the std macro `thread_local!`.

```rust

extern crate regex;

use with_thread_local::with_thread_local;

use regex::Regex;

let user_input = "cat";

let (is_a_pet, needs_a_walk) = with_thread_local! {

    static REGEX_PET: Regex = Regex::new(r"cat|dog").unwrap();

    static REGEX_WALK: Regex = Regex::new(r"dog").unwrap();

    {

        let is_a_pet = REGEX_PET.is_match(user_input);

        let needs_a_walk = REGEX_WALK.is_match(user_input);

        (is_a_pet, needs_a_walk)

    }

};

assert!(is_a_pet && !needs_a_walk);

```

You can also use its variant `move` to move variables inside the block. Though I admit I could

not write a good example:

```rust

extern crate regex;

use with_thread_local::with_thread_local;

use regex::Regex;

let user_input = vec!["cat", "love", "dog"];

let output = with_thread_local! {

    static REGEX_PET: Regex = Regex::new(r"cat|dog").unwrap();

    move {

        user_input

            .into_iter()

            .filter(|s| REGEX_PET.is_match(s))

            .collect::>()

    }

};

assert_eq!(output, ["cat", "dog"]);

```
