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.
Magic Enum 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.

Possibly stupid question, is java the right language for low latency and high throughput web servers?
I was about to suggest Chronicle, but it looks like they have gone closed-source. The older version is still interesting to look through though. Aeron / Disruptor / SBE are good projects for inspiration as well.

GitHub - realtimetech-solution/opack: Fast object or data serialize and deserialize library
Could you evaluate how it compares with SBE?
-
Simple Binary Encoding (SBE) now supports Rust
The Simple Binary Encoding (SBE) project now includes support for generating Rust code. Generated code produced does not use unsafe and has no dependencies on any other crates.

I made an NBT-based data format, but a little more general purpose

Parsing Protobuf at 2+GB/S: How I Learned to Love Tail Calls in C
Consider a valid protobuf message with such a field. If you can locate the field value bytes, you can write a new value to the same location without breaking the message. It's obviously possible to the same with the varint type too, as long as you don't change the number of bytes - not so practical, but useful for enum field which has a limited set of useful values (usually less than 128).
Pregenerating protobuf messages you want to send and then modifying the bytes in-place before sending is going to give you a nice performance boost over "normal" protobuf serialization. It can be useful if you need to be protobuf compatible, but it's obviously better to use something like SBE - https://github.com/real-logic/simple-binary-encoding
