#[derive(Debug)] Developer T-Shirt
#[derive(Debug)] tells the compiler to generate a `Debug` implementation for a type, so you can print it with {:?} instead of writing the formatting by hand.
Usually the first attribute added to a new struct, for the simple reason that a value you can't print is a value you can't inspect when something goes wrong."
The fabric is slightly sheer and may appear see-through, particularly in lighter colours or bright lighting.
Printed on demand — each piece is made to order.
Shipping costs vary by region, so it's worth giving the delivery total at checkout a quick look before confirming your order. Some variants may show limited availability in certain locations—if fulfilment isn't available in your region, our suppliers will try to ship globally from the nearest facility that can produce that specific item. When this happens, delivery costs may be higher than expected due to the increased distance.
We're constantly reviewing suppliers and expanding fulfilment options, and new routes may open over time.
