Circular include issue fixed

Use function declaration syntax in template type specification

Use terse function notation - match std::function, the optional 1st argument for C-style FP is now ONLY in 3rd template argument.

Performance improvement for Delegate specialization without additional C-function ptr argument.

Updated Delegate and new MultiDelegate template.

MultiDelegate template argument to switch queue/event behavior.

Completed port of Delegate and MultiDelegate to Non-Arduino platforms

Directly derive from std::function for DelegateImpl<void, R>, too.
dok-net

Fixed queue and event multiplexer modes (ISQUEUE template argument) for performance.

Signed-unsigned mismatch caught by ESP2866 Arduino CI.
dok-net
committed
Performance and ease of use, more comprehensible ctor and operator=: accept C-func ptr w/o
dok-net
committed
Interface full lockdown: mark implementation details private instead of protected.
dok-net
committed
For use of Delegate as callback in functions that take C-fun ptr and void* arg, added facility to type convert Delegate to R (*)(void*, P...) and function void* arg().
dok-net
committed
Optimize casting to fun ptr and argument for "attachInterruptArg"-like APIs.
dok-net
committed
Bug fix: must reinterpret_cast for R() as R(void*) cast (extra argument is harmless in C calling convention).
dok-net
committed
using operator= is required to suppress auto generation.
dok-net
committed
Delegate to fptr helpers must be in IRAM
dok-net
committed
Delegate refactoring for same ordering of member functions between specializations. Portability fix for Non-ESP Arduino.
dok-net
committed
Bug fix Delegate, custom type converter.
dok-net
committed
Use explicit initialization in ctor for kind member.
dok-net
committed
Fix ctor overloads competing with ctor templates.
dok-net
committed
Assignment operator template caused ambiguity error in MSVC build - drop it, it's strictly not necessary.
dok-net
committed
Delegate template programming for > 3 platforms is interesting.
dok-net
committed
unsigned/int instead of (u)int32_t gives lower memory footprint on 8bit devices.
dok-net
committed
Refactor uses of unsigned for buffer sizes and item counts to size_t.
dok-net
committed
It was found that internal linkage suppresses the effect of the IRAM_ATTR attribute.
dok-net
committed
std::bind is IRAM cache save, lambda is not.
dok-net
committed
Enhancements to MultiDelegate: event multiplexer mode no longer has auto-remove. Invoke returns result of last Delegate call.
dok-net
committed
Added forward iterator and begin() and end() functions to MultiDelegate.
dok-net
committed
Change to make MultiDelegate invoke and erase work off iterators.

Fix both ambiguous operator= and infinite ctor recursion.
dok-net

don't cast to rvalue ref if also move'ing
dok-net

More hints for proper use of Delegate to optimize performance.
