// Define a functor-style callback that will be invoked synchronously by the
// Parse() method. It will be called for each part of the pattern consisting
// of text to match strictly against an input. For example, for the pattern:
// `/foo/:bar.html`
// The callback will be invoked with `/foo`, `/`, and `.html` separately.
// The callback should validate the input and potentially perform any encoding
// necessary. For example, some characters could be percent encoded. The
// final encoded value for the input should be returned.

// Parse a pattern string and return the result. The parse will fail if the
// input |pattern| is not valid UTF-8. Currently only group names may actually
// contain non-ASCII characters, however. Unicode characters in other parts of
// the pattern will cause an error to be returned. A |callback| must be
// provided to validate and encode plain text parts of the pattern. An
// |options| value may be provided to override default behavior.
