# function_ref

A lightweight non-owning reference to a callable.

Clang + GCC: [![Linux Build Status](https://travis-ci.org/TartanLlama/function_ref.png?branch=master)](https://travis-ci.org/TartanLlama/function_ref)

MSVC: [![Windows Build Status](https://ci.appveyor.com/api/projects/status/k5x00xa11y3s5wsg?svg=true)](https://ci.appveyor.com/project/TartanLlama/function_ref)

Use `tl::function_ref` instead of `std::function` whenever you don't need to own the callable. The most common case for this is function parameters which aren't stored anywhere:

```cpp

void foo (function_ref func) {

    std::cout << "Result is " << func(21); //42

}

foo([](int i) { return i*2; });

```
