Declaration

associatedtype RegexOutput

A Regex instance’s output type depends on whether the Regex has captures and how it is created.

A Regex created from a string using the init(_:) initializer has an output type of AnyRegexOutput, whether it has captures or not.
A Regex without captures created from a regex literal, the init(_:as:) initializer, or a RegexBuilder closure has a Substring output type, where the substring is the portion of the string that was matched.
A Regex with captures created from a regex literal or the init(_:as:) initializer has a tuple of substrings as its output type. The first component of the tuple is the full portion of the string that was matched, with the remaining components holding the captures.
