Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Destroy

destroy region

Destroy the region. This will invalidate the object ID.

This is a destructor, once received this object cannot be used any longer.

Add

add rectangle to region

Add the specified rectangle to the region.

Fields of Add

x: i32y: i32width: i32height: i32

Subtract

subtract rectangle from region

Subtract the specified rectangle from the region.

Fields of Subtract
