When I try and build my project, I get these errors in the wgpu crate, which is a dependency of the wonnx crate that I am using.

I tried:
cargo updatewgpu (0.20.1 as a direct dependency in cargo.tomlIf this is a known issue, and I'm being dumb, please point it out in the comments. If you've never heard of it before, please also comment, and I'll end up opening a GitHub issue (maybe a better place to start I know).
Thank you!
You are specifying web_sys_unstable_apis, which is, by definition, unstable. That is, changes can occur in the APIs across minor versions.
This is what happened here. wonnx relies on an old, and unmaintained, version of wgpu (0.16). That versions relies on some old version of web-sys (0.3.61). web-sys has gained new minor versions since, and minor versions promise to keep the API the same, but excluding unstable APIs. Cargo used the newer web-sys versions (because they are SemVer-compatible), which broke wgpu.
The real fault here is probably of wgpu, since when relying on unstable APIs, you should generally specify a precise version requirement (=version) exactly to avoid situations like that. But I can understand people are hesitant to use precise requirements, since they can break in various ways.
The fault is also partially of wonnx, by not updating to the newer wgpu version. This is something you can open an issue about, but I don't know how much work it will be to update to the current wgpu version, since it is SemVer-incompatible.
Other than waiting for wonnx to upgrade their wgpu, the easiest fix is to pin web-sys version's yourself. That means patching wgpu. Instead of cloning wgpu, an easier way will be to copy it from your registry cache, normally located in <home>/.cargo/registry/src/index.crates.io-<some_hash>. Find the wgpu-0.16.3 directory there (it will be there if you already tried to build your project, if not you can specify it as a dependency some temporary project and cargo fetch), copy it, change Cargo.toml in the lines:
[target."cfg(target_arch = \"wasm32\")".dependencies.web-sys]
features = [...]
version = "0.3.61"
...
[target."cfg(target_arch = \"wasm32\")".dev-dependencies.web-sys]
features = [...]
version = "0.3.61"
To:
[target."cfg(target_arch = \"wasm32\")".dependencies.web-sys]
features = [...]
version = "=0.3.61"
...
[target."cfg(target_arch = \"wasm32\")".dev-dependencies.web-sys]
features = [...]
version = "=0.3.61"
Then in your project's Cargo.toml, include this:
[patch.crates-io]
wgpu = { path = "../path/to/your/wgpu/clone" }
You also need to update your web-sys version to =0.3.61.
And that's it!
