What is the opposite to being "consumed" in a sense of being soon to be "consumed" but not yet happened to be. Or, to put it in a different way, is there a nicer way (synonym?) to say "unconsumed"?
Background & context: The subject of "consumption" here is a character (a symbol/letter from a long line of text).
I am working on a parser, so for each given rule the outcome of feeding a character to the parser can be either consumed (we can move on to the next character) or unconsumed meaning we should try to apply another rule if any, for either outcome there must be a type that represents it, the type needs a name, hence the question, I know I can go with unconsumed but it sounds a bit awkward.
