## Ejemplo
|
|
|
|
```go
|
|
type ServerConfig struct {
|
|
Host string `required:"true"`
|
|
Port int `required:"true" min:"1" max:"65535"`
|
|
Email string `format:"email"`
|
|
}
|
|
|
|
v := ConfigValidate(ServerConfig{Host: "localhost", Port: 8080})
|
|
if !v.IsValid {
|
|
for _, e := range v.Errors {
|
|
log.Printf("[%s] %s: %s", e.Tag, e.Field, e.Message)
|
|
}
|
|
}
|
|
```

## Notas
|
|
|
|
Funcion pura — usa solo reflect, sin I/O. Soporta tags: `required:"true"`, `format:"email"`, `format:"url"`, `min:"N"`, `max:"N"`, `oneof:"a b c"`. Solo inspecciona campos exportados. No es recursiva — no baja a structs anidados.
