`rust-analyzer` fails with `ic_cdk_bindgen` #442

Open letmejustputthishere opened 10 months ago

it seems like ic_cdk_bindgen expects an env variable set for the candid path. if you're not building with dfx, the env variables doens't seem to be present and the rust-analyzer VSCode plugin throws the following error:

[ERROR rust_analyzer::main_loop] FetchBuildDataError:
error: failed to run custom build command for `iluvatar_backend v0.1.0 (/Users/moritz/projects/iluvatar/src/iluvatar_backend)`
note: To improve backtraces for build dependencies, set the CARGO_PROFILE_DEV_BUILD_OVERRIDE_DEBUG=true environment variable to enable debug information generation.

i guess this is related.
