<p>Resource in turn has at least one route.
|

|
|
Route consists of an object that implements <code>Handler</code> trait (handler)
|
|||
|
|
and list of predicates (objects that implement <code>Predicate</code> trait).
|
|||
|
|
Route uses builder-like pattern for configuration.
|

|
|
During request handling, resource object iterate through all routes
|
|||
|
|
and check all predicates for specific route, if request matches all
|
|||
|
|
predicates route route considered matched and route handler get called.</p>
