//! Example demonstrating GUID resolution with .meta files
|
|
//!
|
|
//! This example shows how to:
|
|
//! - Load Unity files with their .meta files
|
|
//! - Access GUID to path mappings
|
|
//! - Resolve cross-file references using GUIDs
|
|
//!
|
|
//! Run with: cargo run --example guid_resolution
