I would tag this 'E-Easy' and "docs" if I could tag things. :) |

… r=brson My main goals were: - be clear when we talk about "references" and "pointers" - remove Managed boxes completely and the concept of GC. #13987

I think this is largely good to go. I'll be keeping a future eye out for it. |
Merged

i heard a presentation about rust talking about an optimal gc...is this on ice now? http://channel9.msdn.com/Events/Lang-NEXT/Lang-NEXT-2014/Panel-Systems-Programming-Languages-in-2014-and-Beyond |

There never was a GC, we just said there was. It was a reference count with cycle detection. The plan was to eventually turn it into a GC, but instead, it's just being removed. |

Using `Vec::extend(std::iter::repeat_n(item, N))` allows to use the more natural number of elements to add `N`, as is probably done in the original loop, instead of computing the difference between the existing number of elements and the wanted one. Before MSRV 1.82, the older suggestion to use `Vec::resize()` is still issued. Inspired by rust-lang#6156 (which predates `repeat_n()`). changelog: [`same_item_push`]: recommend using `Vec::extend()` to extend a vector

Rust has never actually had a garbage collector, but we lied about it for years. Time to come clean. I'd like to give all the docs a once-over, and remove all references to garbage collection, except for
Gc<T>, obviously.For example, the lifetimes tutorial: http://static.rust-lang.org/doc/0.10/guide-lifetimes.html
