Module schema 

Available on crate features functional and graph only.

State schema validation for the functional API.

Provides validation of workflow state against a declared schema at workflow start and before applying task output reducers. Wraps the existing StateSchema from adk-graph and adds type-level validation capabilities specific to the functional API.

Example

use adk_graph::functional::StateSchemaValidator;
use adk_graph::state::StateSchema;
use serde_json::json;
use std::collections::HashMap;

let schema = StateSchema::builder()
    .channel("counter")
    .list_channel("messages")
    .build();

let validator = StateSchemaValidator::new(schema)
    .expect_type("counter", ExpectedType::Number)
    .expect_type("messages", ExpectedType::Array);

let mut state = HashMap::new();
state.insert("counter".to_string(), json!(42));
state.insert("messages".to_string(), json!([]));

// Passes validation
validator.validate_state(&state).unwrap();
