Rust - Visualizers no longer working as expected

[DotNetWho]

OS: Windows 10 Enterprise 22H2
VSCode version: 1.93.1
CodeLLDB version: v1.10.0
Compiler: rustc 1.83.0-nightly
Debuggee: x86_64-windows-msvc &/ x86_64-windows-gnu

Running the VSCode debugger, I notice that the visualizers no longer work as I expected.
Here is an example with a simple vector.

fn main() {
    // You can optionally experiment here.
    let input = [2, 4, 6, 8, 10];
    let as_vec: Vec<i32> = input.iter().map(|&x| x).collect();
    println!("{:?}", as_vec);
    println!("What is happening here?");
}

Hovering over the as_vec variable, or adding it to the watch window shows the following:

The log for LLDB adds the following upon adding the watch value:

[DEBUG codelldb::dap_codec] --> {"command":"evaluate","arguments":{"expression":"as_vec","frameId":1001,"context":"watch"},"type":"request","seq":36}

And hovering over:

[DEBUG codelldb::dap_codec] --> {"command":"evaluate","arguments":{"expression":"as_vec","frameId":1001,"context":"hover","line":36,"column":9,"source":{"name":"vecs2.rs","path":"c:\\Dev\\Learning\\Rust\\rustlings\\exercises\\05_vecs\\vecs2.rs"}},"type":"request","seq":39}

I have tried both the msvc and gnu toolchains (added the -gnu target to the msvc toolchain as well) and both produce the same problem. Likewise Rustrover has the same behaviour. An LLDB regression maybe?
I have tried searching your codebase and the past issues for the visualizers but to now avail.

Curiously, the input variable is show correctly, only the memory on the heap is not:

p input
(int[5])  ([0] = 2, [1] = 4, [2] = 6, [3] = 8, [4] = 10)

p as_vec
(alloc::vec::Vec<i32,alloc::alloc::Global>) (5) vec![{...}, {...}, {...}, {...}, {...}, ...] {}

[vadimcn]

Yeah, looks like Vec representation got changed again... Which is why I am actually in the process of switching to rustc-provided data formatters. Here's a build that does that.
But it still doesn't work - I think even rustc's own formatters are broken in 1.82. I was able to reproduce this problem with rust-lldb wrapper.

[DotNetWho]

Yeah, looks like Vec representation got changed again...

I would expect this to be written in the release notes somewhere. I am using nightly however.

Which is why I am actually in the process of switching to rustc-provided data formatters.

Could you point me to the files that are involved in this so that I can check on my side as well?
Is it this on codelldb side: formatters/rust.py
And these on rustc side in : src/etc/lldb_providers.py & src/etc/rust_types.py

[vadimcn]

This change seems to fix it for me:

[Drakesinger]

These are the providers from the rust project itself. Easy way of translating that into your StdVectorSynthProvider?

[vadimcn]

As of v1.11, CodeLLDB will just use formatters shipped with rustc.

[DotNetWho]

Fair enough.

Looked through your last commits for what you changed to use their formatters but without success. Could you show me that so if there are problems I know where to look?
At least to know the paths where they are located once installed.

[vadimcn]

Are you asking, which file my patch above is for?
It's $(rustc --print=sysroot)/lib/rustlib/etc/lldb_providers.py
(1.82.0-beta.5)

[DotNetWho]

Thank you.
