This change:
- introduces `compute_crate_def_map` query and renames
`CrateDefMap::crate_def_map_query` for consistency,
- annotates `crate_def_map` as `salsa::transparent` and adds a
top-level `crate_def_map` wrapper function around that starts the
profiler and immediately calls into `compute_crate_def_map` query.
This allows us to better understand where we spent the time, in
particular, how much is spent in the recomputaiton and how much in
salsa.
Example output (where we don't actually re-compute anything, but the
query still takes a non-trivial amount of time):
```
211ms - handle_inlay_hints
150ms - get_inlay_hints
150ms - SourceAnalyzer::new
65ms - def_with_body_from_child_node
65ms - analyze_container
65ms - analyze_container
65ms - Module::from_definition
65ms - Module::from_file
65ms - crate_def_map
1ms - parse_macro_query (6 calls)
0ms - raw_items_query (1 calls)
64ms - ???
```

Rust Analyzer
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 in the compiler-team repository:
https://github.com/rust-lang/compiler-team/tree/master/content/working-groups/rls-2.0
Work on the Rust Analyzer is sponsored by
Language Server Quick Start
Rust Analyzer is a work-in-progress, so you'll have to build it from source, and 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 language server itself
- latest stable npm and VS Code for VS Code extension
To quickly install rust-analyzer with 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 `ra_lsp_server`.
$ 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 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.
