Provides CowVec, a lazy copy-on-write wrapper around Vec.
```rust extern crate cowvecitem; use cowvecitem::CowVec;
let mut big_vec = vec!["lion", "tiger", "dragon"];
let mut copyonwriteref = CowVec::from(&bigvec);
// Just ensure there are no dragons, then print stuff for mut item in copyonwriteref.itermut() { // Do lots of stuff if *item == "dragon" { //Dragons are not allowed here. *item = "sparrow"; // The entire big_vec will be cloned here } }
for item in copyonwrite_ref.iter() { println!("Animal: {}", item); //Don't worry, no dragons here }
// You can also get an owned vector, in this example only when changes were detected if copyonwriteref.isowned() { let myprivatevec : Vec<&str> = copyonwriteref.toowned(); }
```
