What is the difference between Go's embedded structs and nested structs?

In Go, a struct can embed other structs to inherit their fields and methods. There are two ways to embed structs: embedded structs and nested structs.

Embedded structs are used to compose a new struct by embedding an existing struct. The fields and methods of the embedded struct become part of the new struct and can be accessed using the dot notation.

Nested structs, on the other hand, are used to define a new struct inside an existing struct. The nested struct is encapsulated within the parent struct and cannot be accessed directly from outside.

In other words, embedded structs allow for code reuse and composition by inheriting fields and methods, while nested structs provide a way to organize and encapsulate related data within a struct.
