J. Nick Koston 29882cf036 [core] Rename Callback fields to fn_ and ctx_ for consistency 2026-03-15 23:10:13 -10:00
J. Nick Koston 7edcc15cee [core] Address review nits 
- Remove stale #include <functional> from microphone headers
- Add default initializers to Callback::fn and Callback::ctx
- Remove redundant cb.ctx = nullptr (now default-initialized)
 2026-03-15 23:08:48 -10:00
J. Nick Koston 610258b683 [core] Convert remaining callback registration methods to templates 
Convert rotary_encoder register_listener, canbus add_callback,
sdl add_key_listener, and udp add_listener from std::function to
templates to avoid the heap-allocation fallback path.

MQTT backend set_on_* methods are virtual and cannot be templatized.

J. Nick Koston 073dd3995e [microphone] Remove unnecessary std::function wrapping in callbacks 
Pass wrapping lambdas directly to CallbackManager::add() instead of
first wrapping in std::function. The lambdas capture [this, callback]
(two pointers) so they hit the heap path either way, but this avoids
double-wrapping and the extra std::function overhead.

Also fix "deallaction" typo.

J. Nick Koston 1357de1fcd [microphone] Remove empty microphone.cpp 
The only function was inlined into the header as a template.
 2026-03-15 22:53:59 -10:00
J. Nick Koston fd51f0603e [core] Convert remaining add_*_callback methods to templates 
Convert haier, nextion, microphone, ezo, uart, speaker, zigbee,
and hlk_fm22x callback methods that were missed by the initial
conversion (they used add_*_callback instead of add_on_*_callback).
 2026-03-15 22:48:58 -10:00
J. Nick Koston 30e6e0a6b7 [core] Add static_assert for void* / uintptr_t size parity 
Ensures the inline Callback storage path is only used on platforms
where void* has no trap representations (all bit patterns valid).
 2026-03-15 22:41:15 -10:00
J. Nick Koston 70733fa913 [core] Fix Callback invocation for function pointer callables 
Use (*ptr)(args...) instead of ptr->operator()(args...) so the
inline path works correctly for function pointers, which are
trivially copyable and pointer-sized but lack operator().
 2026-03-15 22:39:31 -10:00
J. Nick Koston 3cebea9538 [core] Use __builtin_memcpy in Callback::create for cleaner code 
Replace char-by-char loops with __builtin_memcpy in the inline
Callback storage path. Generates identical code but is cleaner
and avoids clang-analyzer false positives without NOLINT annotations.
 2026-03-15 22:38:11 -10:00
J. Nick Koston 3c90438947 [core] Convert remaining add_on_*_callback methods to templates 
Convert all remaining component add_on_*_callback methods from
std::function to templates so lambdas flow through without wrapping.
This avoids a heap allocation regression where passing std::function
through Callback::create would heap-allocate the std::function itself.

Also add NOLINT annotations for clang-analyzer false positive on
byte-wise copy in Callback::create.
 2026-03-15 22:36:48 -10:00
J. Nick Koston bfc5a210bc [core] Replace std::function with lightweight Callback in CallbackManager 
Replace std::function with a lightweight type-erased Callback struct
(8 bytes on 32-bit vs 16 for std::function) in CallbackManager and
LazyCallbackManager. Using C++20 if constexpr, small trivially-copyable
callables like [this] lambdas (81% of all callback registrations) are
stored inline in the function pointer context without heap allocation.

This eliminates std::function null checks (and __throw_bad_function_call)
from all entity callback paths, and templatizes add_on_*_callback methods
across all entity types so lambdas flow through without being wrapped in
std::function first.

Also converts EntityStateBase from hand-rolled nullable CallbackManager
pointers to LazyCallbackManager for consistency.

Measured flash savings:
- ESP8266 simple:        -160 B
- ESP8266 ratgdo:        -592 B
- ESP32 IDF (large):     -456 B
- ESP32 IDF (minimal):   -212 B
