Mustermann capture options accept arbitrary Ruby classes and parse them on match, while all other capture groups return raw String parameters.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

Mustermann capture options only accept built-in converter types (Date, Gem::Version, Float, Integer, Symbol), raising Mustermann::CompileError on arbitrary classes like Time while typecasting extracted parameters into Ruby class instances and round-tripping them through expand.
Passing an array of capture types such as [Integer, Date, :slug] creates a polymorphic capture that matches and dynamically casts each segment to its matching Ruby type or string.
Symbol constraints that are not built-in converter names (such as :alpha or :alnum) compile to POSIX character classes and return uncasted String parameters.
Typed parameter hashes containing Date, Gem::Version, Float, Symbol, and Integer instances serialize back into canonical URL paths via expand without requiring string conversion.
