You can generate OpenAPI documentation automatically in Rust by using compile-time macros to derive schemas from data types and annotate route handlers, producing an openapi.json file during the build process without manual configuration.

The best way to reduce routing boilerplate when building Rust APIs is to use macro-driven app setup and route annotations, which automates route creation and eliminates repetitive manual handler registrations.

Yes, zero-config OpenAPI generation works in Rust by leveraging compile-time macros to handle schema derivation and route mapping during the build step, entirely removing the need for runtime configuration.

You derive API schemas from custom data types in Rust by applying a Schema derive macro to your structs, which automatically generates the required API schemas and documentation at compile time.

Yes, you can use compile-time macros to define routes in Rust web frameworks by annotating pub async route handlers with route attributes, automating endpoint registration and OpenAPI spec generation.

Compile-time macros for OpenAPI generation in Rust require all schema derivations and route definitions to be statically known at build time, meaning dynamic route creation or runtime schema modifications are not supported.
