2017-04-13Auto merge of #41009 - scottmcm:toowned-clone-into, r=alexcrichtonbors-0/+6
Add a resource-reusing method to `ToOwned` `ToOwned::to_owned` generalizes `Clone::clone`, but `ToOwned` doesn't have an equivalent to `Clone::clone_from`. This PR adds such a method as `clone_into` under a new unstable feature `toowned_clone_into`. Analogous to `clone_from`, this has the obvious default implementation in terms of `to_owned`. I've updated the `libcollections` impls: for `T:Clone` it uses `clone_from`, for `[T]` I moved the code from `Vec::clone_from` and implemented that in terms of this, and for `str` it's a predictable implementation in terms of `[u8]`. Used it in `Cow::clone_from` to reuse resources when both are `Cow::Owned`, and added a test that `Cow<str>` thus keeps capacity in `clone_from` in that situation. The obvious question: is this the right place for the method? - It's here so it lives next to `to_owned`, making the default implementation reasonable, and avoiding another trait. But allowing method syntax forces a name like `clone_into`, rather than something more consistent like `owned_from`. - Another trait would allow `owned_from` and could support multiple owning types per borrow type. But it'd be another single-method trait that generalizes `Clone`, and I don't know how to give it a default impl in terms of `ToOwned::to_owned`, since a blanket would mean overlapping impls problems. I did it this way as it's simpler and many of the `Borrow`s/`AsRef`s don't make sense with `owned_from` anyway (`[T;1]:Borrow<[T]>`, `Arc<T>:Borrow<T>`, `String:AsRef<OsStr>`...). I'd be happy to re-do it the other way, though, if someone has a good solution for the default handling. (I can also update with `CStr`, `OsStr`, and `Path` once a direction is decided.)
2017-04-12Add ToOwned::clone_into (unstable as toowned_clone_into)Scott McMurray-0/+6
to_owned generalizes clone; this generalizes clone_from. Use to_owned to give it a default impl. Customize the impl for [T], str, and T:Clone. Use it in Cow::clone_from to reuse resources when cloning Owned into Owned.

2016-10-11Rollup merge of #36699 - bluss:repeat-str, r=alexcrichtonGuillaume Gomez-0/+20
Add method str::repeat(self, usize) -> String It is relatively simple to repeat a string n times: `(0..n).map(|_| s).collect::<String>()`. It becomes slightly more complicated to do it “right” (sizing the allocation up front), which warrants a method that does it for us. This method is useful in writing testcases, or when generating text. `format!()` can be used to repeat single characters, but not repeating strings like this.
