OAPH

Helps to subtituated query params and schema definitions to openapi3 yaml.

This is feature-less simple crate with no ambitions to support whole openapi 3 specs and cover all cases (at least cover my personal use-cases).

use serde::{Serialize, Deserialize};
use oaph::{OpenApiPlaceHolder, schemars::{self, JsonSchema}};


#[allow(dead_code)]
#[derive(Deserialize, JsonSchema)]
struct SearchQuery {
    /// some description for this flag (see https://graham.cool/schemars/examples/6-doc_comments/)
    flag: bool,
}

#[allow(dead_code)]
#[derive(Deserialize, JsonSchema)]
struct SearchResponse {
    success: bool,
    count: usize,
    items: Vec<Item>,
}

#[allow(dead_code)]
#[derive(Deserialize, JsonSchema)]
struct Item {
    id: usize,
    value: String,
}

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let openapi3_yaml = OpenApiPlaceHolder::new()
        .query_params::<SearchQuery>("SearchQuery")?
        .schema::<SearchResponse>("SearchResponse")?
        .render_to(r#"
openapi: 3.0.0
info:
  title: oaph example
  version: 1.0.0
paths:
  /search:
    get:
      tags:
      - demo
      description: demo api
      parameters:
        {{SearchQuery}}
      responses:
        '201':
          content:
            application/json:
              schema:
                {{SearchResponse}}
definitions:
  {{oaph::definitions}}
"#)?;

    println!("{}", openapi3_yaml);
    Ok(())
}

And output would be

      tags:

                type: object
                required:
                  - count
                  - items

                properties:

                  items:
                    type: array
                    items:
                      $ref: "#/definitions/Item"
definitions:
  Item:
    type: object
    required:
      - id
      - value
    properties:
      id:
        type: integer
        format: uint
        minimum: 0.0
      value:
