EasyLazy - Lazy initialization made easy

Looking at the available options for lazy initialization, I found that the most required jumping through odd, unnecessary hoops. EasyLazy aims to make lazy initialization of a variable lightweight and easy.

EasyLazy has only 3 requirements:

• T must implement Clone
• T must implement Default with a cheap operation
• The Lazy variable must be mutable so that it can be initialized

Usage

use easylazy::Lazy;
let mut my_lazy_variable = Lazy::new(Box::new(|| 10));
// my_lazy_variable is uninitialized here
assert_eq!(my_lazy_variable.get(), 10);
my_lazy_variable.get_mut() = 20;
assert_eq!(my_lazy_variable.get(), 20);

Lazy is Send & Sync so long as T is Send & Sync. Please make sure that your calculation is also thread safe before assuming YOUR Lazy variable is Send & Sync.
