Crate oapi_codegen 

oapi-codegen — generate idiomatic Rust from OpenAPI 3 specifications.

The pipeline is: load a spec (loader), lower its component schemas into an intermediate representation (lower::schema → ir) and, for the server generator, its operations (lower::paths → ir), then emit formatted Rust source (emit). Config mirrors oapi-codegen’s YAML configuration.

Re-exports

pub use crate::config::Config;

pub use crate::error::Error;

pub use crate::error::Result;

Modules

cli

Definition of the command-line interface.

config

Generator configuration, compatible with oapi-codegen’s YAML configuration files.

deps

Computing the external crate dependencies the generated code requires.

emit

Emitting the crate::ir as formatted Rust source.

error

Error types for the generator.

filter

Spec-level operation and schema filtering.

ir

Intermediate representation (IR) of generated Rust types.

loader

Loading OpenAPI documents and resolving $refs.

lower

Lowering OpenAPI documents into the intermediate representation (IR).

naming

Conversion of OpenAPI names into valid, idiomatic Rust identifiers and derivation of per-operation artifact names.

Enums

Drift

What a comparison of generated code against an output file found.

Functions

check_output

Compare code with the content of output_path and report the difference.

generate

Generate Rust from a spec file according to configuration, returning the source.

generate_models_string

Generate Rust models from a spec file and return the formatted source.

generate_models_to_file

Generate Rust models from a spec file and write them to output_path, creating parent directories as needed.

generate_to_file

Generate Rust from a spec file according to configuration and write it to output_path, creating parent directories as needed.

write_output

Write generated source to output_path, creating parent directories.
