Function from_parameter 

pub fn from_parameter(
    parameter: Value,
    options: &Options,
) -> Result<Value, Error>

Convert an OpenAPI 3.0 Parameter Object or Response Object.

With a schema member the result is a single JSON Schema. With a content member the result is a map keyed by MIME type, where each value is a JSON Schema with its own $schema. The outer map has no $schema.

A truthy description on the parameter is copied onto each result.

Errors

Returns Error::InvalidInput when strict mode is on and the parameter has neither a schema nor a content member. Returns Error::InvalidType under the same conditions as from_schema.

Example

use openapi_schema_to_json_schema::{from_parameter, Options};
use serde_json::json;

let param = json!({
    "name": "id",
    "in": "query",
    "schema": { "type": "string", "nullable": true }
});
let out = from_parameter(param, &Options::new()).unwrap();
assert_eq!(out["type"], json!(["string", "null"]));
