Crate policyai 

PolicyAI: A framework for turning unstructured data into structured data via composable policies.

PolicyAI provides a mechanism for writing policies that transform unstructured text into structured outputs. Policies are composable, meaning multiple policies can be applied together with configurable conflict resolution strategies.

Core Concepts

• PolicyType: Defines the structure of data that policies will work with
• Policy: A semantic injection coupled with structured actions
• Field: A typed field in a policy with default values and conflict resolution
• Manager: Coordinates the application of multiple policies to unstructured data
• Report: The result of applying policies, including the structured output

Example

use policyai::{PolicyType, Field, OnConflict, Manager};

let policy_type = PolicyType {
    name: "EmailPolicy".to_string(),
    fields: vec![
        Field::Bool {
            name: "unread".to_string(),
            default: Some(true),
            on_conflict: OnConflict::Default,
        },
        Field::StringEnum {
            name: "priority".to_string(),
            values: vec!["low".to_string(), "high".to_string()],
            default: None,
            on_conflict: OnConflict::LargestValue,
        },
    ],
};
