• openapi-generator generate -i ./openapi/spec3.json -g rust -o ./openapi-generator/rust-spec-3
• cd ./openapi-generator/rust-spec-3
• cargo build

Versions

• openapi-generator version

  • 4.3.1

• cargo version

  • cargo 1.46.0 (149022b1d 2020-07-17)

Reproduce with openapi-generator using ./openapi/spec3.json and the rust generator, then enter ./openapi-generator/rust-spec-3 and run cargo build. Inspect the generated models and the reported duplicate definitions, unresolved crate paths, missing serde_json module, and missing AnyOf types. Done means the generated Stripe client builds successfully.
