Detailed Description

Concept for types that can be both received and posted as event data.

A type satisfies event_data if it can be received and is trivially copyable, allowing ESP-IDF to memcpy it into the event queue. Trivially copyable types satisfy both this and receivable_event_data without needing from_opaque.

Types that are only received (e.g., system event data from ESP-IDF that wraps non-trivial C++ types) need only satisfy receivable_event_data.

Template Parameters

T	The type to check.
