A matcher that uses a custom function

fto consume the firstNelements from the input before passing the remainder to the next matcher in the chain.For example:
Matcher.greedy { (stack, offset, avail) => if(avail >= 2 && stack(offset) == "foo" && stack(offset + 1) == "bar"){ Some("yes!" -> 2) } else { None } }- A
The matcher function's result type
- f
The matching function. Given a reference to the stack elements, an offset position, and the number of elements available starting from the offset,
fshould return an option containing a pair of the matched value and the unconsumed portion of the stack.- returns
A new matcher which uses
fto determine how (and how much of) the stack is matched
