(Usage: -) + + | + This is the 'or' operator allowing multiple validators to be used and + accepted. (Usage: rbg|rgba) <-- this would allow either rgb or rgba + colors to be accepted. This can also be combined with 'and' for example + ( Usage: omitempty,rgb|rgba) + + structonly + When a field that is a nest struct in encountered and contains this flag + any validation on the nested struct such as "required" will be run, but + none of the nested struct fields will be validated. This is usefull if + inside of you program you know the struct will be valid, but need to + verify it has been assigned. + + omitempty + Allows conditional validation, for example if a field is not set with + a value (Determined by the required validator) then other validation + such as min or max won't run, but if a value is set validation will run. + (Usage: omitempty) + + dive + This tells the validator to dive into a slice, array or map and validate that + level of the slice, array or map with the validation tags that follow. + Multidimensional nesting is also supported, each level you with to dive will + require another dive tag. (Usage: dive) + Example: [][]string with validation tag "gt=0,dive,len=1,dive,required" + gt=0 will be applied to [] + len=1 will be applied to []string + required will be applied to string + Example2: [][]string with validation tag "gt=0,dive,dive,required" + gt=0 will be applied to [] + []string will be spared validation + required will be applied to string + NOTE: in Example2 if the required validation failed, but all others passed + the hierarchy of FieldError's in the middle with have their IsPlaceHolder field + set to true. If a FieldError has IsSliceOrMap=true or IsMap=true then the + FieldError is a Slice or Map field and if IsPlaceHolder=true then contains errors + within its SliceOrArrayErrs or MapErrs fields. + + required + This validates that the value is not the data types default value. + For numbers ensures value is not zero. For strings ensures value is + not "". For slices, arrays, and maps, ensures the length is not zero. + (Usage: required) + + len + For numbers, max will ensure that the value is + equal to the parameter given. For strings, it checks that + the string length is exactly that number of characters. For slices, + arrays, and maps, validates the number of items.
