* Remove parse error on array initializer attributesRyan Cumming2019-06-303-76/+0
| | | | | This is actually allowed by the `rustc` parser but most attributes will fail later due to attributes on expressions being experimental.
* Support attributes on array membersRyan Cumming2019-06-307-0/+205
| | | | | | | | | | | | Array members are allow to have attributes such as `#[cfg]`. This is a bit tricky as we don't know if the first expression is an initializer or a member until we encounter a `;`. This reuses a trick from `stmt` where we remember if we saw an attribute and then raise an error if the first expression ends up being an initializer. This isn't perfect as the error isn't correctly located on the attribute or initializer; it ends up immediately after the `;`.

* | Swallow expected `rustfmt` errorsRyan Cumming2019-06-261-10/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My workflow in Visual Studio Code + Rust Analyzer has become: 1. Make a change to Rust source code using all the analysis magic 2. Save the file to trigger `cargo watch`. I have format on save enabled for all file types so this also runs `rustfmt` 3. Fix any diagnostics that `cargo watch` finds Unfortunately if the Rust source has any syntax errors the act of saving will pop up a scary "command has failed" message and will switch to the "Output" tab to show the `rustfmt` error and exit code. I did a quick survey of what other Language Servers do in this case. Both the JSON and TypeScript servers will swallow the error and return success. This is consistent with how I remember my workflow in those languages. The syntax error will show up as a diagnostic so it should be clear why the file isn't formatting. I checked the `rustfmt` source code and while it does distinguish "parse errors" from "operational errors" internally they both result in exit status of 1. However, more catastrophic errors (missing `rustfmt`, SIGSEGV, etc) will return 127+ error codes which we can distinguish from a normal failure. This changes our handler to log an info message and feign success if `rustfmt` exits with status 1. Another option I considered was only swallowing the error if the formatting request came from format-on-save. However, the Language Server Protocol doesn't seem to distinguish those cases.

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1406: reuse AnalysisHost in batch analysis r=matklad a=matklad We do some custom setup in `AnalysisHost`, like setting up LRU size. I figure it's a good idea to not duplicate this work in batch analysis, *if* we want to keep batch and non-batch close. Long-term, I see a value in keeping batch a separate, lighter weight thing. However, because now we use batch to measure performance, keeping them closer makes more sense. I'd also like to add ability to get completions by using batch analysis, and that will require ra_ide_api as well. @flodiebold were there some reason why we haven't started with this approach from the start?
