Template Struct Value

• Defined in File dimensions.h

Struct Documentation

template<typename T, typename Tag>
struct Value

Wraps a geometry value and prevents it from being accidentally used for invalid operations (such as setting a width to a height or adding two x positions together). Of course, explicit casts are possible to get around these restrictions (see the as_*() functions).

Public Types

using ValueType = T

using TagType = Tag
