# 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, configurable 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
* [cpplang on Slack](https://Cpplang.slack.com) (use the `#boost` channel)
* [Boost Users Mailing List](https://lists.boost.org/mailman/listinfo.cgi/boost-users)
* [Boost Developers Mailing List](https://lists.boost.org/mailman/listinfo.cgi/boost)
## Distribution
Besides GitHub, there are two other distribution channels:
* LEAF is included in official [Boost](https://www.boost.org/) releases, starting with Boost 1.75.
* For maximum portability, the library is also available in single-header format: [leaf.hpp](https://raw.githubusercontent.com/boostorg/leaf/gh-pages/leaf.hpp).
