Question 1

How to build Coost with cmake instead of xmake?

Accepted Answer

Create a build directory, run 'cmake ..' with optional flags like -DBUILD_ALL=ON or -DWITH_LIBCURL=ON for HTTP/SSL features, then compile with 'make -j8'. Detailed steps are in the README's cmake section.

Question 2

Is Coost logging better than spdlog?

Accepted Answer

Yes, benchmarks show Coost's log library is significantly faster, with up to 23.8x speedup on Linux and 3.9x on Windows in multi-threaded tests. It also includes CHECK macros for enhanced assertions.

Question 3

Can I use Coost for embedded systems development?

Accepted Answer

Potentially, due to its 1MB static library size and efficiency, but ensure your toolchain supports C++11 and check dependencies for features like networking, which may add overhead.

Question 4

Coost vs Boost: which is lighter for base utilities?

Accepted Answer

Coost is much lighter—about 1MB vs Boost's larger footprint—and offers comparable features like logging and JSON, but Boost has a broader ecosystem and supports newer C++ standards.

Question 5

How to implement a coroutine-based HTTP server with Coost?

Accepted Answer

Use the http::Server class with an on_req callback, then start it on a port; for SSL, provide key and certificate files. Example code in the README shows handling GET requests and setting responses.

Question 6

Does Coost support JSON RPC for microservices?

Accepted Answer

Yes, it includes an RPC framework with coroutine-based servers and clients, supporting both binary and HTTP POST methods, as demonstrated in the network programming section.

Question 7

What's the license for Coost, and are there any restrictions?

Accepted Answer

It uses the MIT license, but includes code from other projects like tbox with their own licenses, so review LICENSE.md for details, especially if redistributing.
