Quick Start
Contributors: This Release
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
- cpplang on Slack (use the
#boostchannel) - Boost Users Mailing List
- Boost Developers Mailing List
Distribution
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).
