Validating Structs Idiomatically

In Go, ensuring the validity of struct values is often done by explicitly checking each field individually. While this approach is straightforward for small structures, it can become tedious for larger ones with numerous fields.

Can we improve the validation process?

The standard approach, illustrated in the following code snippet, involves manually checking each field:

type Event struct {
    Id     int
    UserId int
    Start  time.Time
    End    time.Time
