Function parse_uri_reference

Return a reference to a parsed URL string

Synopsis

            system::result
parse_uri_reference(core::string_view s);
        

Description

This function parses a string according to the grammar below and returns a view referencing the passed string upon success, else returns an error. Ownership of the string is not transferred; the caller is responsible for ensuring that the lifetime of the character buffer extends until the view is no longer being accessed.

Example

system::result< url_view > = parse_uri_reference( "ws://echo.example.com/?name=boost#demo" );

BNF
