The left matcher (i.e. the first choice)
The right matcher (i.e. the fallback)
A matcher that uses a custom function f to consume the first N elements
from the input before passing the remainder to the next matcher in the chain.
A matcher that uses a custom function f to consume the first N elements
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
}
}The matcher function's result type
The matching function. Given a reference to the stack elements, an offset position, and
the number of elements available starting from the offset, f should return
an option containing a pair of the matched value and the unconsumed portion of the stack.
A new matcher which uses f to determine how (and how much of) the stack is matched
A matcher that quickly rejects any input
A matcher that quickly matches any input as () without consuming any stack.
A matcher that matches any input as long as the next matcher in the chain will match some segment of that input.
