libboost-leaf/1.83.0

A lightweight error handling library for C++11

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

cpplang on Slack (use the #boost channel)
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).
