Generic type constraints allow you to specify constraints on a type that can vary depending on the specific type being instantiated.

Syntax:

type Name[T any] string

Parameters:

• T: The type variable. It can be any type, including primitive types, structures, and functions.

Examples:

• Integer constraint:**

type Age[T int] int

This constraint ensures that T is an integer type.

• String constraint:**

type Name[T string]

This constraint ensures that T is a string type.

• Struct constraint:**

type User[T struct] {
Name string
Age  int
}

This constraint ensures that T is a struct type with at least two fields named Name and Age.

• Function constraint:**

type Calculator[T any] func(T, T) T

This constraint ensures that T is a type that implements the Calculator interface.

Benefits of using generic type constraints:

• Code reusability:** You can apply the same constraint to multiple types, reducing code duplication.
• Type safety:** Constraints ensure that only valid types are used, preventing runtime errors.
• Improved maintainability:** By separating the constraint from the type, it becomes easier to understand and modify.

Note:

• Generic type constraints are not applicable to primitive types (e.g., int, string).
• Constraints can be applied to function types only if the function is generic.
• Constraints can be used with type parameters, allowing you to specify different constraints for different types.
