Error when generating Markdown document

[facundo-villa]

Hi!
I love this crate. I'd been looking for something like this for a while. But I'm hitting an error when trying to generate MD files from my crates' json docs.

Error: invalid type: map, expected a string at line 1 column 6631

Location:
    ~/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/rustdoc-md-0.1.0/src/main.rs:24:23

This is the rust-doc json file from which I'm trying to generate the markdown. I tried other crates but they all failed with similar errors.
This is the command I used to generate the json files: RUSTDOCFLAGS="-Z unstable-options --output-format json" cargo doc --no-deps
I'm on Cargo cargo 1.91.0-nightly (a6c58d430 2025-08-26)

The json schema for the rustdocs is changing pretty frequently, looks like since I made this crate its no longer compatible with the latest rustdoc. You can try cloning down this repo, and replacing the rustdoc_json_types.rs file with the one here: https://github.com/rust-lang/rustdoc-types/blob/trunk/src/lib.rs

We're maybe not hitting the same error, but it does look like it:

...
    "1001": {
      "attrs": [
        {
          "other": "#[attr = Inline(Hint)]"
        }
      ],
...

attrs is now a list of maps.

rustdoc-md now uses the rustdoc-types crate. Currently its just using 0.56.0, but a nice solution to support multiple versions might be to actually include multiple versions of the crate, and choose which one to use based on the format_version of the json.
