Title: This Week in Rust 20 Date: 2013-10-19 10:49 Category: This Week in Rust

Welcome to another issue of This Week in Rust, a weekly summary of Rust's progress and happenings in the community.

What's cooking in master?

48 PRs were merged this week.

Breaking changes

• Slices are now represented as number of elements, not number of bytes.
• fmt! has been completely removed.
• Some fields in std::comm have been made private.
• std::sys::refcount has been moved to std::managed::refcount.
• A bunch of functions have moved from std::sys to std::mem.
• once fn is now a feature gate rather than a -Z flag.
• Path has been completely rewritten.
• extra::flatpipes has been removed.

Other changes

• jemalloc has been removed from the runtime. The associated issue is quite scary.
• rustdoc struct field visibility is now corrected (it stripped fields where it should not have).
• rustdoc also uses the actual privacy rules to strip methods.
• format! now gives much better error messages for invalid format strings.
• The fmt::Default trait, used for default formatting with format!, is now documented.
• include_bin! has been optimized, and the k-nucleotides benchmark now compiles 187x faster.
• Vectors now have starts_with and ends_with methods, which take slices.
• An abort intrinsic has been added.
• Vectors now have a get_opt method.
