3380: Unsizing in method resolution & autoderef for indexing r=matklad a=flodiebold

 - do autoderef for indexing
 - do array unsizing (`[T; N]` -> `[T]`) in both method resolution and indexing. It turns out array unsizing is actually the only unsizing coercion that rustc does for method receivers, so this is simpler than I expected.

Sadly, this doesn't fix indexing slices/arrays yet, there are still some trait solving problems...

rust-analyzer logo

rust-analyzer is an experimental modular compiler frontend for the Rust language. It is a part of a larger rls-2.0 effort to create excellent IDE support for Rust. If you want to get involved, check the rls-2.0 working group:

https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Fwg-rls-2.2E0

Work on rust-analyzer is sponsored by

Ferrous Systems

Language Server Quick Start

rust-analyzer is a work-in-progress, so you might encounter critical bugs. That said, it is complete enough to provide a useful IDE experience and some people use it as a daily driver.

To build rust-analyzer, you need:

  • latest stable Rust for the language server itself
  • latest stable npm and VS Code for VS Code extension

To quickly install the rust-analyzer language server and VS Code extension with standard setup (code and cargo in $PATH, etc), use this:

# clone the repo
$ git clone https://github.com/rust-analyzer/rust-analyzer && cd rust-analyzer

# install both the language server and VS Code extension
$ cargo xtask install

# alternatively, install only the server. Binary name is `rust-analyzer`.
$ cargo xtask install --server

For non-standard setup of VS Code and other editors, or if the language server cannot start, see ./docs/user.

Documentation

If you want to contribute to rust-analyzer or are just curious about how things work under the hood, check the ./docs/dev folder.

If you want to use rust-analyzer's language server with your editor of choice, check ./docs/user folder. It also contains some tips & tricks to help you be more productive when using rust-analyzer.
