* | | | | Handle coercing function types to function pointers in matchFlorian Diebold2020-05-084-11/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | E.g. in ```rust match x { 1 => function1, 2 => function2, } ``` we need to try coercing both to pointers. Turns out this is a special case in rustc as well (see the link in the comment).

We tried to model this just using the never type, but that doesn't work fully (e.g. in `let x = { loop {}; "foo" };` x should still have type `&str`); so this introduces a `diverges` flag that the type checker keeps track of, like rustc does. We also add some checking for `break`, but no support for break-with-value or labeled breaks yet.

This is approximately a 90% fix for the issue described there. This PR creates a new crate `ra_env` with a function `get_path_for_executable()`; see docs there. `get_path_for_executable()` improves and generalizes the function `cargo_binary()` which was previously duplicated in the `ra_project_model` and `ra_flycheck` crates. (Both of those crates now depend on the new `ra_env` crate.) The new function checks (e.g.) `$CARGO` and `$PATH`, but also falls back on `~/.cargo/bin` manually before erroring out. This should allow most users to not have to worry about setting the `$CARGO` or `$PATH` variables for VSCode, which can be difficult e.g. on macOS as discussed in #3118. I've attempted to replace all calls to `cargo`, `rustc`, and `rustup` in rust-analyzer with appropriate invocations of `get_path_for_executable()`; I don't think I've missed any in Rust code, but there is at least one invocation in TypeScript code which I haven't fixed. (I'm not sure whether it's affected by the same problem or not.) https://github.com/rust-analyzer/rust-analyzer/blob/a4778ddb7a00f552a8e653bbf56ae9fd69cfe1d3/editors/code/src/cargo.ts#L79 I'm sure this PR could be improved a bunch, so I'm happy to take feedback/suggestions on how to solve this problem better, or just bikeshedding variable/function/crate names etc. cc @Veetaha Fixes #3118.

I took a stab at fixing that by adding an implementation of `HasVisibility` for `EnumVariant` so it works more or less the same way it does for struct fields. In other words, the `search_range` here does not contain the ref since it's not considered visible: https://github.com/rust-analyzer/rust-analyzer/blob/efd8e34c396f1524623a495e47111f1047cf2879/crates/ra_ide_db/src/search.rs#L209-L214 Before that I tried to populate `ItemScope` with visible enum variants but that ended up with breaking tests all over the place and also it looked illogical in the end: `ItemScope` is not populated with, say, public struct fields and the same should be true for `enum` variants. I've added two more or less identical tests: one for the case with a struct field rename and one for enum variant rename; the test for struct should probably be removed and the names should be changed.
