How to initialize array in rust

What's the best way to initialize large array?

For Example : I want an array of 100000 elements. But if we use [0; 100000] it will definitely give me stack overflow error because fixed arrays are allocated in stack as far as I know in rust. So what's the best way to create an array of 100000 in rust ?
