What types in the Go language contain a pointer to a memory segment?

In the Go language, the following types contain a pointer to a memory segment:

• Slices — a structure containing a pointer to an array, length, and capacity.
• Maps — internally implemented through pointers to a hash table.
• Channels — contain a pointer to an internal channel structure.
• Interfaces — contain a pointer to a method table and a pointer to data.

Primitive types (int, float, bool, etc.) and arrays do not contain pointers internally unless pointers are explicitly used.

For example, a slice looks like this:

var s []int = []int{1, 2, 3}
// s contains a pointer to the array [1,2,3], length, and capacity

This allows efficient work with large data sets without copying.
