A lightweight error handling library for C++11.

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

• 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.

• cpplang on Slack (use the #boost channel)
• Boost Users Mailing List
• Boost Developers Mailing List

Besides GitHub, there are two other distribution channels:

• LEAF is included in official Boost releases, starting with Boost 1.75.
• For maximum portability, the library is also available in single-header format: simply download leaf.hpp (direct download link).
