Enum Schema 

pub enum Schema {
    Reference {
        reference: String,
    },
    Object(Box<SchemaObject>),
    Any(Value),
}

JSON Schema object

Flexible representation that can hold any valid JSON Schema. This type supports both schema references (using $ref) and complete inline schema definitions.

Schemas define the structure and validation rules for message payloads, following the JSON Schema specification.

Example

Reference Schema

use asyncapi_rust_models::Schema;

let schema = Schema::Reference {
    reference: "#/components/schemas/ChatMessage".to_string(),
};

Object Schema

use asyncapi_rust_models::{Schema, SchemaObject};
use indexmap::IndexMap;

let schema = Schema::Object(Box::new(SchemaObject {
    schema_type: Some(serde_json::json!("object")),
    properties: None,
    required: Some(vec!["username".to_string(), "room".to_string()]),
    description: Some("A chat message".to_string()),
    title: Some("ChatMessage".to_string()),
    enum_values: None,
    const_value: None,
    items: None,
    additional_properties: None,
    one_of: None,
    any_of: None,
    all_of: None,
    additional: IndexMap::new(),
}));

Variants

Reference

Reference to another schema ($ref)

Points to a reusable schema definition in the components section. Format: “#/components/schemas/{schemaName}”

Fields

reference: String

$ref path

Object(Box<SchemaObject>)

Full schema object (boxed to reduce enum size)

Contains a complete JSON Schema definition with all properties inline

Any(Value)

Catch-all for valid JSON Schemas that don’t match the above variants

Handles minimal schemas like {}, {"title": "..."}, or boolean schemas (true/false) that are valid per the JSON Schema spec but carry no structural information. schemars emits these for open-ended types such as serde_json::Value.
