dawdle v0.5.0 Dawdle.Handler behaviour View Source
Defines a handler for queued events.
To define an event handler, use Dawdle.Handler
and provide a list of event
types (structs) that you wish to handle. Then, override the callback
handle_event/1
.
Examples
defmodule MyApp.TestEvent do
defstruct :foo, :bar
end
defmodule MyApp.TestEventHandler do
use Dawdle.Handler, only: [MyApp.TestEvent]
alias MyApp.TestEvent
def handle_event(%TestEvent{foo: 1}) do
# Do something...
end
def handle_event(%TestEvent{bar: 2}) do
# Do something else...
end
def handle_event(%TestEvent{}) do
# Default case
end
end
