Description
Objects of this type represent valid URL strings constructed from a parsed, external character buffer whose storage is managed by the caller. That is, it acts like a core::string_view in terms of ownership. The caller is responsible for ensuring that the lifetime of the underlying character buffer extends until it is no longer referenced.
Example 1
Construction from a string parses the input as a URI-reference and throws an exception on error. Upon success, the constructed object points to the passed character buffer; ownership is not transferred.
url_view u( "https://www.example.com/index.htm?text=none#a1" );Example 2
Parsing functions like parse_uri_reference return a result containing either a valid url_view upon succcess, otherwise they contain an error. The error can be converted to an exception by the caller if desired:
system::result< url_view > rv = parse_uri_reference( "https://www.example.com/index.htm?text=none#a1" );
