Introduction

ustd provides minimal and highly portable implementations of the following classes:

ustd::array<T>, a lightweight c++11 array implementation.
ustd::queue<T>, a lightweight c++11 ring buffer queue implementation.
ustd::map<K,V>, a lightweight c++11 dictionary map implementation.

Additionally a drop-in replacement for std::function<> is provided as ustd::function<> for Atmel AVRs

functional.h

The libraries are header-only and should work with any c++11 compiler and support platforms starting with 8k attiny, avr, arduinos, up to esp8266, esp32 and mac and linux.

Make sure to provide the required platform define before including ustd headers.
