Path Dependent Types
Path-dependent types are a way to express relationships between objects in a program. They are used to create specific types that are dependent on the path of the object from which they are created. For example, if you have object A and its subtype B, a path-dependent type can be created for B that is dependent on the path from A to B.
In other words, a path-dependent type is a type that is specific to a particular path from an object to its subtype. This allows for more specific and expressive types in a program, which can be used to better represent the relationships between objects in the program.
Scala Path Dependent Type
Scala Path Dependent Types (PDTs) are an advanced feature of the Scala language that allows users to create types that are dependent on the path in which they are accessed. The type of a variable or object is not determined by its own structure or characteristics, but rather by the path in which it is accessed. This allows for a more flexible and powerful type system, allowing for more complex and expressive types.
