# LEAF

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

## Documentation

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

## Features

* Small single-header format, **no dependencies**.
* Designed for maximum efficiency ("happy" path and "sad" path).
* No dynamic memory allocations, even with heavy payloads.
* O(1) transport of arbitrary error types (independent of call stack depth).
* Can be used with or without exception handling.
* Support for multi-thread programming.

## Support
