            url_base&
set_params(std::initializer_list ps) noexcept;

An empty list of params is distinct from having no params.

Reserved characters in the string are percent-escaped in the result.

Example

assert( url( "http://example.com" ).set_params( {"id", "42"} ).query() == "id=42" );

Postconditions

this->has_query() == true

Exception Safety

Strong guarantee. Calls to allocate may throw.

Complexity

Linear.
