dynstack

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.

let mut stack = DynStack::<dyn Debug>::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]
