A Rust-based URL parser using the pest parsing library with ability to extract various components like protocol, domain, subdomain, port, path segments, query parameters, and fragments.

The grammar is defined using pest and covers the following components:

• Protocol: Either "http" or "https".
• Subdomain: Optional subdomain that appears before the main domain.
• Domain: The main domain name.
• Port: Optional port number, appearing after a colon.
• Path: Segmented by /, representing directories or resources.
• Query Parameters: Key-value pairs in the query string, separated by &.
• Fragment: The portion of the URL following a #.

The parser processes URLs by breaking them into components using predefined grammar. Then the results are encapsulated in a structured ParsedURL object.

protocol://subdomain.domain:port/path/to/resource?param1=value1&param2=value2#section
   └── protocol = "https"
   └── subdomain = "sub"
   └── domain = "example.com"
   └── port = 8080
   └── path = ["path", "to", "resource"]
   └── query = [("param1", "value1"), ("param2", "value2")]
   └── fragment = "section"
