Implement element getters for n-tuples#6591

brendanzab · 2013-05-18T09:07:12Z

This commit implements element getters for tuples with an arity of 2 to 12. The getters return references to the elements, so no copying occurs. The traits are re-exported in core::prelude so you can use them from regular Rust code.

Here is an example of one of the getters in use:

assert_eq!((2, "hi", 75.0).n1(), &"hi");

This commit implements element getters for tuples with an arity of 2 to 12. The getters return references to the elements, so no copying occurs.

`manual_filter_map` and `manual_find_map` changelog: Add `manual_filter_map` and replace `find_map` with `manual_find_map` Replaces rust-lang#6453 Fixes rust-lang#3188 Fixes rust-lang#4193 ~Depends on rust-lang#6567 (to fix an internal lint false positive)~ This replaces `filter_map` and `find_map` with `manual_filter_map` and `manual_find_map` respectively. However, `filter_map` is left in place since it is used for a variety of other cases. See discussion in rust-lang#6453.

Deprecate `filter_map` Since rust-lang#6591, `filter_map` does not even lint `filter().map()`. The cases that are still linted make no sense IMO. So this just removes/deprecates it. changelog: Deprecate `filter_map` lint Closes rust-lang#3424 Fixes rust-lang#7050
