Deserializing fails for JSON generated by rustdoc 1.70

[GoldsteinE]

Repro:

pub struct Foo;

impl Foo {
    pub fn bar(&self) {
        println!("test");
    }
}

Error:

unknown variant `decl`, expected one of `module`, `extern_crate`, `import`, `union`, `struct`, `struct_field`, `enum`, `variant`, `function`, `trait`, `trait_alias`, `impl`, `typedef`, `opaque_ty`, `constant`, `static`, `foreign_type`, `macro`, `proc_macro`, `primitive`, `assoc_const`, `assoc_type` at line 1 column 616

Please provide detailed information about what versions you use for everything, as well as full commands and source code you use to reproduce the problem. In my own project I run extensive rustdoc-json deserialization tests each night with the latest Rust nightly toolchain, and I have not detected any issues.

rustdoc 1.70 won't give json output, as it's not stable (unless your using unspeakable env-var hacks, which arn't supported)

What version of the rustdoc-types crate are you using?

What is the format_version of the json produced?

[GoldsteinE]

Versions that I’ve tried:

1. rustdoc 1.70.0-nightly (9df3a39fb 2023-04-11)
2. rustdoc 1.70.0 stable + RUSTC_BOOTSTRAP hack

.format_version is 24 in both cases.

I realize now that the latest version of rustdoc-types is probably meant for a different nightly.

[aDotInTheVoid]

Yeah see CHANGELOG.md, for format version 24, you want `rustdoc-types="0.20.0".

(At some point we should syncronize FORMAT_VERSION and the version on crates.io)

Thanks for helping!
