accepted. (Usage: rbg|rgba) <-- this would allow either rgb or rgba
|
| 149 | 149 |
colors to be accepted. This can also be combined with 'and' for example
|
| 150 | 150 |
( Usage: omitempty,rgb|rgba)
|
|
151 |
|
|
152 |
structonly
|
|
153 |
When a field that is a nest struct in encountered and contains this flag
|
|
154 |
any validation on the nested struct such as "required" will be run, but
|
|
155 |
none of the nested struct fields will be validated. This is usefull if
|
|
156 |
inside of you program you know the struct will be valid, but need to
|
|
157 |
verify it has been assigned.
|
| 151 | 158 |
|
| 152 | 159 |
omitempty
|
| 153 | 160 |
Allows conitional validation, for example if a field is not set with
|
| 21 | 21 |
orSeparator = "|"
|
| 22 | 22 |
noValidationTag = "-"
|
| 23 | 23 |
tagKeySeparator = "="
|
|
24 |
structOnlyTag = "structonly"
|
| 24 | 25 |
omitempty = "omitempty"
|
| 25 | 26 |
validationFieldErrMsg = "Field validation for \"%s\" failed on the \"%s\" tag\n"
|
| 26 | 27 |
validationStructErrMsg = "Struct:%s\n"
|
|
| 215 | 216 |
|
| 216 | 217 |
} else {
