Function get_function_hash_db 

pub fn get_function_hash_db(db: &MirageDb, function_id: i64) -> Option<String>

Get the function hash for path caching (backend-agnostic)

This is the main entry point for getting function hashes. It works with both SQLite and geometric backends.

For SQLite backend: returns the stored hash if available For geometric backend: always returns None (Magellan manages its own caching)

Arguments

• db - Database reference (works with both backends)
• function_id - ID of the function

Returns

• Some(hash) - The function hash if available (SQLite only)
• None - Hash not available or geometric backend

Examples

if let Some(hash) = get_function_hash_db(&db, 123) {
    println!("Hash: {}", hash);
}
