Guardia URN Generator

This project provides a library for generating and validating Uniform Resource Names (URNs) to identify resources within the Guardia system.

Features

• URN Generation: Create URNs with mandatory field validation
• Validation: Ensures required fields and product-specific rules
• Environment Variable Support: Configuration via environment variables
• URN Parser: Analyze and validate existing URNs
• Integration Tests: BDD tests using Cucumber

Usage

API

use guardia_rs_urn::UrnBuilder;

// Generating a URN
let urn = UrnBuilder::new()
    .with_organization_id("1234567890")
    .with_tenant_id("1234567890")
    .with_product("lke")
    .with_entity_type("user")
    .with_entity_id("1234567890")
    .build()?;

println!("Generated URN: {}", urn);

// Parsing an existing URN
let urn_str = "urn:guardia:org:1234567890:tenant:1234567890:lke:user:1234567890";
let parsed_urn = GuardiaUrn::parse(urn_str)?;

// Accessing URN fields
println!("Organization ID: {}", parsed_urn.organization_id.unwrap());
println!("Product: {}", parsed_urn.product.unwrap());

Environment Variables

export ORGANIZATION_ID=1234567890
export TENANT_ID=1234567890
export PRODUCT=lke
export ENTITY_TYPE=user
export ENTITY_ID=1234567890

# The URN will be generated automatically when running the program

Supported Products

• LKE: Basic URN without additional fields
• PSA/BSA: Requires rail and provider
• DWA: Requires rail, protocol, and provider

Development

Prerequisites

• Rust and Cargo installed
• Cucumber for integration testing
