Description

I'm developing a small project here: https://github.com/kubajal/minimax-in-rust I cannot run code generated by openapi-generator-cli v5.0.1 through cargo run --example server in Docker image rust:1.50 . I get the following error:

root@67eadc0267a7:/rust-app# cargo run --example server
error: failed to parse manifest at `/rust-app/Cargo.toml`

Caused by:
  can't find `client` example, specify example.path

I'd expect this to succeed as that is the step described in the README.md generated by npx @openapitools/openapi-generator-cli generate -i swagger.yml -g rust-server.

openapi-generator version

v5.0.1 I downloaded it through https://openapi-generator.tech/docs/installation/.

OpenAPI declaration file content or url

https://github.com/kubajal/minimax-in-rust/blob/main/swagger.yml

Generation Details

I just used npx @openapitools/openapi-generator-cli generate -i swagger.yml -g rust-server.

Steps to reproduce

git clone https://github.com/kubajal/minimax-in-rust.git
cd minimax-in-rust
docker build -t rust-app
docker run -it rust-app
# in the container
cd /rust-app
cargo run --example server
