# LEAF

> A lightweight error handling library for C++11.

## Documentation

https://boostorg.github.io/leaf/

## Features

* Portable single-header format, no dependencies.
* Tiny code size when configured for embedded development.
* No dynamic memory allocations, even with very large payloads.
* Deterministic unbiased efficiency on the "happy" path and the "sad" path.
* Error objects are handled in constant time, independent of call stack depth.
* Can be used with or without exception handling.

## Support
