###### url::params (2 of 4 overloads)

Return the query as a container of parameters.

###### Synopsis

    params_view
    params() const;

###### Description

This function returns a bidirectional view of key/value pairs over the query. The returned view references the same underlying character buffer; ownership is not transferred. Any percent-escapes in strings returned when iterating the view are decoded first.

###### Example

    params_view pv = url_view( "/sql?id=42&name=jane%2Ddoe&page+size=20" ).params();

###### Complexity

Constant.

###### Exception Safety

Throws nothing.

###### BNF

    query           = *( pchar / "/" / "?" )

    query-param     = key [ "=" value ]
    query-params    = [ query-param ] *( "&" query-param )
