Constructor

Synopsis

Declared in <boost/url/url_view.hpp>

url_view(core::string_view s);

Description

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.

Example

url_view u( "http://www.example.com/index.htm" );

Effects

return parse_uri_reference( s ).value();

Complexity

Linear in s.size().
