Function New

model/textparse/interface.go:166–201

New returns a new parser of the byte slice. This function no longer guarantees to return a valid parser. It only returns a valid parser if the supplied contentType and fallbackType allow. An error may also be returned if fallbackType had to be used or there was some other error parsing the supplie
