- Defer to Ipv4Addr::fmt when printing an Ipv4 address - Fast path: write directly to f without an intermediary buffer when there are no alignment options - Simplify finding the inner zeroes-span
This adds new optional methods on `Extend`: `extend_one` add a single element to the collection, and `extend_reserve` pre-allocates space for the predicted number of incoming elements. These are used in `Iterator` for `partition` and `unzip` as they shuffle elements one-at-a-time into their respective collections.

…lacrum Various minor improvements to Ipv6Addr::Display Cleaned up `Ipv6Addr::Display`, especially with an eye towards simplifying and reducing duplicated logic. Also added a fast-path optimization, similar to rust-lang#72399 and rust-lang#72398. - Defer to `Ipv4Addr::fmt` when printing an Ipv4 address - Fast path: write directly to `f` without an intermediary buffer when there are no alignment options - Simplify finding the inner zeroes-span
…r=petrochenkov Only capture tokens for items with outer attributes Suggested by @petrochenkov in rust-lang#43081 (comment)
…epmaster Add tests for 'impl Default for [T; N]' Related: rust-lang#71690. This pull request adds two tests: - Even it T::default() panics, no leaks occur. - [T; 0] is Default even if T is not. I believe at some moment `Default` impl for arrays will be rewritten to use const generics instead of macros, and these tests will help to prevent behavior changes.
