#rust2018

2017 was a giant 12 months for the Rust programs programming language. Now, members of the open supply undertaking wish to consolidate final years progress making Rust simpler to be taught and use and publish the primary main replace to the secure 2015 Rust release. Were making Rust a a lot nicer place to be, mentioned Aaron Turon, a Rust core crew member and engineering supervisor at Mozilla.…

The Rust project is soliciting wishlists for 2018. Rather than list big things that everybody wants like NLL or a more stable tokio, I’m going to list some things that I think are small and could be knocked out in relatively short order.

Prefetching:

Rust has a `std::intrinsics::prefetch_read_data`, but it’s marked as experimental.  Because prefetching only changes the performance of a program and not its correctness, it should be easy to standardize a version of this with a “might do nothing if its not supported on this platform/compiler/etc” caveat.

Debugging:

The DWARF generated by rustc is pretty bad and I think there’s a lot of easy wins here.

Thin references should become `DW_TAG_reference`. This has been stalled on figuring out what to do with fat references but it shouldn’t be blocked by that.

const/mut should be noted in the generated DWARF (see issue 32921)

Tom Tromey is already working on enums so yay!

Stdlib:

Stabilize `TryFrom`
