Evobox

A pointer type which allows for safe transformations of its content without reallocation. This crate does not depend on the standard library, and can be used in #![no_std] contexts. It does however require the alloc crate.

Examples

```rust use evobox::{EvolveBox, L};

let s: EvolveBox>>> = EvolveBox::new("7"); let owned = s.evolve(|v| v.tostring()); asserteq!(owned.as_str(), "7");

let seven = owned.tryevolve(|s| s.parse()).expect("invalid integer"); asserteq!(*seven, 7); ```
