TruncateEllipsis truncates the given string and adds ellipsis where the input is cut

func UnmarshalAndValidate

func UnmarshalAndValidate(data []byte, obj interface{}) error

UnmarshalAndValidate is a convenience function to unmarshal an object and validate it

func UnmarshalAndValidateWithLimit

func UnmarshalAndValidateWithLimit(reader io.ReadCloser, s interface{}, limit int64) error

UnmarshalAndValidateWithLimit unmarshals a struct with a limit on how many bytes can be read from the given reader

func Validate

func Validate(obj interface{}) error

Validate will run validation on the given object and return a set of field specific errors in the format: field <fieldname> <tag specific message>

For example: "field 'flows' is required"
