Behaviour for alert handler display modules.
Renders a handler's own dashboard panel (e.g. a firing timeline). Paired
with a CodeNameRaven.Handler module the same way CodeNameRaven.Display
pairs with CodeNameRaven.Monitor — self-bundled in one module, or as a
separate package-sibling module declaring compatible_handlers/0.
display_name/0 is shared with CodeNameRaven.Handler's own callback of
the same name — combining both behaviours in a single (self-bundled)
module means whichever use runs last wins, the same "conflicting
behaviours" compiler warning CodeNameRaven.Monitor/CodeNameRaven.Display
would hit if combined without their display_params_* naming split. No
module combines Handler and HandlerDisplay today, so this hasn't been
disambiguated — worth revisiting if that ever changes in practice.
Summary
Functions
Returns true if the module implements the HandlerDisplay behaviour.
