Functions ¶
func Check ¶
func Check(definition Of) error
Checks a map of label / errors and returns a validation error which contains every errors as needed.
func Patch ¶
Same as Maybe but for monad.Patch. Executes the function only if the value is set and not nil. Looks like I can't pass by an interface to share the logic between Maybe and Patch since Go can't infer the T. I prefer to make the usage easier by duplicating the logic in this specific case. FIXME: When go can infer correctly from an interface [T], merge Maybe and Patch.
