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 sent this object cannot be used any longer.

Add

Fields

x: i32

y: i32

width: i32

height: i32

add rectangle to region

Add the specified rectangle to the region.

Subtract

Fields

x: i32

y: i32

width: i32

height: i32

subtract rectangle from region

Subtract the specified rectangle from the region.
