Parser

A single, self-contained, immutable parser. The primary method is parse, which returns a T on success and a stack trace on failure.

Some small optimizations are performed in-line: collapsing parsers.Combinators.Either cells into large ones and collapsing parsers.Combinators.Sequence cells into parsers.Combinators.Sequence.Flats. These optimizations together appear to make things faster but any 10%, whether or not you activate tracing

def parse(input: String, index: Int = 0, trace: Boolean = true): Result[T]

Parses the given input starting from the given index
Parses the given input starting from the given index
input
The string we want to parse
index
The index in the string to start from. By default parsing starts from the beginning of a string, but you can start from halfway through the string if you want.
trace
Whether or not you want a full trace of any error messages that appear. Without it, you only get the single deepest parser in the call-stack when it failed, and its index. With trace, you get every parser all the way to the top, though this comes with a ~20-40% slowdown.
def shortTraced: Boolean

Whether or not this parser should show up when Failure.trace is called
