//! Default size type to custom stackbox capacity
//! 
//! The Space type of `StackBox<T, Space>` is not retricted
//! to the following types, instead, it can be any sized type or 
//! even an array.
//! The `resize()` method on `StackBox<T, Space>` is used to transforms itself
//! to the one of bigger capacity
//!
//! # Example
//!
//! ```
//! use smallbox::StackBox;
//! use smallbox::space::*;
//!
//! let s = StackBox::<[usize], S8>::new([0usize; 8]).unwrap();
//! assert!(s.resize::<S16>().is_ok());
//! ```
