Constructor
This function constructs a URL from the string s, which must contain a valid URI or relative-ref or else an exception is thrown. Upon successful construction, the view refers to the characters in the buffer pointed to by s. Ownership is not transferred; The caller is responsible for ensuring that the lifetime of the buffer extends until it is no longer referenced.
