Ralf Jung bac2f39350 Rollup merge of #76310 - scottmcm:array-try_from-vec, r=dtolnay ... Add `[T; N]: TryFrom<Vec<T>>` (insta-stable) This is very similar to the [existing](https://doc.rust-lang.org/nightly/std/convert/trait.TryFrom.html#impl-TryFrom%3CBox%3C%5BT%5D%3E%3E) `Box<[T; N]>: TryFrom<Box<[T]>>`, but allows avoiding the `shrink_to_fit` if you have a vector and not a boxed slice. Like the slice equivalents of this, it fails if the length of the vector is not exactly `N`. This uses `Vec<T>` as the `Error` type to return the input, like how the `Rc<[T]> -> Rc<[T; N]>` (and Arc) ones also reflect the input directly in the error type. ```rust #[stable(feature = "array_try_from_vec", since = "1.47.0")] impl<T, const N: usize> TryFrom<Vec<T>> for [T; N] { type Error = Vec<T>; fn try_from(mut vec: Vec<T>) -> Result<[T; N], Vec<T>>; } ``` Inspired by this zulip thread: https://rust-lang.zulipchat.com/#narrow/stream/219381-t-libs/topic/APIs.20for.20getting.20stuff.20from.20a.20Vec.20by.20owned/near/209048103		2020-09-19 11:47:39 +02:00
