Default is the ruleset that this application uses by default.

Ruleset is a collection of a whitespace detector, a linefeed detector and a slice of rules.

Rule describes a single scanner rule that can theoretically be applied.

RuneScanner is a capsule that limits the interaction of the scanner to a subset of two core functions.

DetectorFunc is a function that can detect if a given rune has a implementation specific attribute.

FuncRule is an type alias that works as implementation for a ruleset.Rule.
