## Summary [summary]: #summary Provide an extensible mechanism for tweaking linking behavior of native libraries both in `#[link]` attributes (`#[link(modifiers = "+foo,-bar")]`) and on command line (`-l static:+foo,-bar=mylib`). ## Motivat...
## Summary This RFC is to gather final feedback on stabilizing the new feature resolver in Cargo. This new feature resolver introduces a new algorithm for computing [package features][docs-old-features] that helps to avoid some unwanted uni...
# Major Change Proposal RFC - Feature Name: N/A - Start Date: 2020-05-07 - RFC PR: [rust-lang/rfcs#2904](https://github.com/rust-lang/rfcs/pull/2904) - Rust Issue: N/A ## Summary [summary]: #summary Introduce the **major change process** fo...
## Summary [summary]: #summary Adds a new syntactical element called an "inline `const`", written as `const { ... }`, which instructs the compiler to execute the contents of the block at compile-time. An inline `const` can be used as an exp...
## Summary [summary]: #summary The RFC proposes a plan to adopt rust-analyzer as Rust's official LSP implementation. The transition to rust-analyzer will take place in a few stages: * **Feedback** -- encourage people to use rust-analyzer an...
## Summary [summary]: #summary We allow destructuring on assignment, as in `let` declarations. For instance, the following are now accepted: ```rust (a, (b.x.y, c)) = (0, (1, 2)); (x, y, .., z) = (1.0, 2.0, 3.0, 4.0, 5.0); [_, f, *baz(), a[...
## Summary [summary]: #summary Deduplicate common dependency and metadata directives amongst a set of workspace crates in Cargo with extensions to the `[workspace]` section in `Cargo.toml`. ## Motivation [motivation]: #motivation Cargo has...
## Summary [summary]: #summary This RFC proposes a policy for managing permissions to the [Rust-Lang GitHub Organization](https://www.github.com/rust-lang) and repositories within this organization. This RFC was written in consultation with...
# Rust 2020 Roadmap - Feature Name: N/A - Start Date: 2020-01-22 - RFC PR: [rust-lang/rfcs#2857](https://github.com/rust-lang/rfcs/pull/2857) - Rust Issue: N/A ## Summary [summary]: #summary Lays out the Rust roadmap for 2020 in pursuit of...
## Summary [summary]: #summary This RFC proposes a new function attribute, `#[instruction_set(set)]` which allows you to declare the instruction set to be used when compiling the function. It also proposes two initial allowed values for the...
## Summary [summary]: #summary This RFC specifies a new syntax for inline assembly which is suitable for eventual stabilization. The initial implementation of this feature will focus on the ARM, x86 and RISC-V architectures. Support for mor...
## Summary [summary]: #summary Change item resolution for generics and trait objects so that a trait bound does not bring its supertraits' items into scope if the subtrait defines an item with this name itself. ## Motivation [motivation]: #...
## Summary [summary]: #summary Deprecate the existing `asm!` macro and provide an identical one called `llvm_asm!`. The feature gate is also renamed from `asm` to `llvm_asm`. Unlike `asm!`, `llvm_asm!` is not intended to ever become stable....
## Summary [summary]: #summary Add the ability to export symbols from executables, not just dylibs, via a new compiler flag: `-C export-executable-symbols`. ## Motivation [motivation]: #motivation Java and C# can't statically link against C...
## Summary [summary]: #summary Cargo should alert developers to upstream dependencies that trigger future-incompatibility warnings. Cargo should list such dependencies even when these warnings have been suppressed (e.g. via cap-lints or `#[...
## Summary [summary]: #summary This RFC proposes to demote the `i686-apple-darwin` rustc target from Tier 1 to Tier 3, and to demote the `armv7-apple-ios`, `armv7s-apple-ios` and `i386-apple-ios` rustc targets from Tier 2 to Tier 3. ## Moti...
## Summary [summary]: #summary To create a [project group] with the purpose of designing subsequent RFCs to extend the language to support inline assembly in Rust code. ## Motivation [motivation]: #motivation In systems programming some tas...
## Summary [summary]: #summary Make the `IpAddr`, `Ipv4Addr`, `Ipv6Addr`, `SocketAddr`, `SocketAddrV4`, `SocketAddrV6`, `Ipv6MulticastScope` and `AddrParseError` types available in `no_std` contexts by moving them into a `core::net` module....
## Summary [summary]: #summary To form a project group with the purpose of designing subsequent RFCs around the topic of safe transmute between types. * This RFC explicitly builds off of processes introduced in the [FFI unwinding project gr...
## Summary [summary]: #summary Add implicit named arguments to `std::format_args!`, inferred from the format string literal. This would result in downstream macros based on `format_args!` to accept implicit named arguments, for example: let...
"Rust's abstraction layers feel both transparent and productive. It's like being on a glass-bottomed boat, you see the sharks, but they can't get you.
