The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to define API stability for a C++ library?
https://github.com/ned14/outcome/tree/develop/abi-compliance uses both in a CI pass to ensure Outcome never changes anything which breaks either API or ABI with earlier versions.
-
What are some cool modern libraries you enjoy using?
outcome and/or expected
-
Outcome enters sustaining phase, goes ABI stable
A "Sample Usage" appears on the front page of the docs: https://ned14.github.io/outcome/

Does Anyone Use Boost Outcome?
I recently came across boost outcome as I was searching for a better error handling method. It took me a minute to get a hang of it but now I love it. After creating my own policy and a few aliases for easier use.
-
Is this error handling strategy good?
std::optional and std::variant can be a bit awkward to use in this scenario, though. Consider a dedicated type like boost::outcome (standalone versions) or one of the implementations of the proposed std::expected.

Modern C++ "result" type based on Swift / Rust
Minimum possible compile time impact is a key goal of https://github.com/ned14/outcome. We ship a single header edition which only includes the low impact standard headers as listed at https://github.com/ned14/stl-header-heft. We also don't use union storage for non-TC non-MB types in order to avoid complex metaprogramming execution by the compiler per instantiation.

C++ Memory Safety
It's really weird that I wrote the above, and then this bug was reported to Outcome: https://github.com/ned14/outcome/issues/244. Here is my exact complaint about lack of lifetime tracking in C++.

What C++ library do you wish existed but hasn’t been created yet?
I'm not sure this is quite what you're asking for, but this library has been super helpful to me in the past : https://github.com/Neargye/magic_enum
- Usable Magic Enums for C++
-
Fully Permissive License C++ Logger For Embedded System
Also, a shoutout to Magic Enum: https://github.com/Neargye/magic_enum
- Favorite Ways of Stringifying Enums
-
enum_name (yet another enum to/from string conversion utility >=C++11)
What does this have to offer over magic_enum?
-
quill v2.7.0 released - Asynchronous Low Latency C++ Logging Library
But it's a hack, and I prefer not to use hacks in production, because of their significant limitations:
-
Enums print numbers instead of words
You can either write a to string(view) function for your enum or use https://github.com/Neargye/magic_enum
-
Enums with methods
Why reinvent the wheel? magic_enum
-
Error: Boost bimap can't convert const CompatibleKey to Key&
Also if you want to convert enum members to string representation I suggest you just use magic_enum instead, much smaller dependency.
-
Macro to write enum and converter from and to string
Magic Enum provides that.
What are some alternatives?
When comparing outcome and Magic Enum C++ you can also consider the following projects:
leaf - Lightweight Error Augmentation Framework
Nameof C++ - Nameof operator for modern C++, simply obtain the name of a variable, type, function, macro, and enum
C++ Format - A modern formatting library
Protobuf - Protocol Buffers - Google's data interchange format
Experimental Boost.DI - C++14 Dependency Injection Library
cereal - A C++11 library for serialization
stb - stb single-file public domain libraries for C/C++
FlatBuffers - FlatBuffers: Memory Efficient Serialization Library
Serial Communication Library - Cross-platform, Serial Port library written in C++
Boost.Serialization - Boost.org serialization module
ZXing - ZXing ("Zebra Crossing") barcode scanning library for Java, Android
pfr - std::tuple like methods for user defined types without any macro or boilerplate code
