## A stack for trait objects that minimizes allocations

**COMPATIBILITY NOTE:** `dynstack` relies on an underspecified fat pointer representation. Though

it isn't expected to change in the foreseeable future, this crate expects Rust 1.34's representation.

### Usage

`dynstack` can mostly replace anywhere you'd use a stack, or a vector that doesn't

require removal from its center.

```rust

let mut stack = DynStack::::new();

dyn_push!(stack, "hello, world!");

dyn_push!(stack, 0usize);

dyn_push!(stack, [1, 2, 3, 4, 5, 6]);

for item in stack.iter() {

    println!("{:?}", item);

}

// prints:

//  "hello, world!"

//  0

//  [1, 2, 3, 4, 5, 6]

```
