So far the only change in the new `HirDisplay` method is that paths are qualified, but more changes will be necessary (omitting the function name from function types, returning an error instead of printing `"{unknown}"`, probably more). Is that approach okay? Co-authored-by: Timo Freiberg <[email protected]>

| |\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 4377: Implement better handling of divergence r=matklad a=flodiebold Divergence here means that for some reason, the end of a block will not be reached. 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 PR unifies the way all engines work. And adds an option to configure each engine separably. For example, this adds visualizers for both `CodeLLDB` and `C++ tools Windows debugger` ```json "rust-analyzer.debug.engineSettings": { "cppvsdbg": { "visualizerFile": "${workspaceRoot}/rdisk.natvis" }, "lldb": { "initCommands": [ "command script import ${workspaceRoot}/rdisk.vis.py" ] } } ``` Co-authored-by: vsrs <[email protected]> Co-authored-by: vsrs <[email protected]>

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.
