4412: infer: Make expected rhs type for plain assign the lhs type r=flodiebold a=kiljacken
This fixes an issue where the following code sample would fail to infer
the type contained in the option:
```rust
fn main() {
let mut end = None; // Was Option<{unknown}>, is now Option<bool>
loop {
end = Some(true);
}
}
```

4409: Hot fix panic for function_signature r=edwin0cheng a=edwin0cheng
I am totally agree this comment:
f1cb5b8a29/crates/ra_ide/src/display/function_signature.rs (L3-L4)
But let hot fix all panic for right now, it is so disturbing when browsing code...

4175: Introduce HirDisplay method for rendering source code & use it in add_function assist r=flodiebold a=TimoFreiberg
Next feature for #3639.
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?

4379: Handle coercing function types to function pointers in match r=matklad a=flodiebold
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).

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.

4366: Unified debug lens r=matklad a=vsrs
Right now every debug engine gets the debug executable and exports the errors on its own.
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"
]
}
}
```

4376: Fix type of byte literals r=matklad a=flodiebold
They're `&[u8; N]`, not `&[u8]` (see #4374).

4329: Look for `cargo`, `rustc`, and `rustup` in standard installation path r=matklad a=cdisselkoen
Discussed in #3118. 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.) a4778ddb7a/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.
