What is the difference between Go's method set and method table for structs?

In Go, a method set is the set of methods that are associated with a type, while a method table is a lookup table used by the Go runtime to find the implementation of a method for a given value.
When a type is defined in Go, it has a method set consisting of all the methods that are associated with that type. The method set includes all the methods that are directly declared for that type as well as any methods that are promoted from its embedded types. A value of a given type can be passed to any function or method that accepts a parameter of that type or any of its super-types. The set of methods that can be called on a value is determined by its type's method set.
In contrast, the method table is used by the Go runtime to find the implementation of a method for a given value. When a method is called on a value, the Go runtime looks up the implementation of the method in the method table for that value's type. This allows the runtime to efficiently dispatch method calls at runtime.
In summary, a method set is the set of methods associated with a type, while a method table is a lookup table used by the Go runtime to find the implementation of a method for a given value.
