How can I validate struct tags in Go?
You can use the validator package in Go to validate struct tags. Would you like an example?
Yes, please provide an example of how to use it.
First, install the package with go get github.com/go-playground/validator/v10. Then, you can define a struct with tags like this:
type User struct {
Name string `validate:"required"`
Email string `validate:"required,email"`
}
You can then create a validator instance and validate the struct.
What if the validation fails?
If validation fails, the validator will return an error containing details about which fields failed and why.
