stack-any
A library that provides a type that owns same size type on the stack for type erasure.
Usage
let mut stacks = [
stack_any::stack_any!(Vec<i32>, vec![]),
stack_any::stack_any!(Vec<char>, vec![]),
];
stacks[0].downcast_mut::<Vec<i32>>().unwrap().push(5);
stacks[1].downcast_mut::<Vec<char>>().unwrap().push('x');
assert_eq!(stacks[0].downcast_ref(), Some(&vec![5]));
assert_eq!(stacks[1].downcast_ref(), Some(&vec!['x']));
