When should you prefer FFI::Platypus, and when should you avoid it?

FFI::Platypus is a Perl module that provides a Foreign Function Interface (FFI) to call functions in shared libraries or dynamic link libraries (DLLs) from Perl code. It allows you to access native libraries written in languages like C, C++, and Rust directly from Perl without needing XS (the Perl C API). However, there are certain situations where you should prefer using FFI::Platypus and others where it might be better to avoid it.

When to Prefer FFI::Platypus

• Ease of Use: FFI::Platypus is easier to use compared to XS, making it a good choice for quick integration.
• No XS Maintenance: If you're looking to avoid the complexities and maintenance associated with writing XS code, FFI::Platypus is a suitable alternative.
• Dynamic Libraries: It is particularly useful when you need to interface with publicly available dynamic libraries.
• Portability: FFI::Platypus is more portable as it does not rely on C compiler settings and can work across different platforms without specific compilation requirements.

When to Avoid FFI::Platypus

• Performance Critical:** In scenarios requiring high performance and low latency, XS might perform better than FFI::Platypus.
• Complex Data Types: If you need to work with complex or extensive data structures, XS may provide better support and efficiency.
• Interfacing with Perl Internals: When dealing with Perl data structures or needing deep integration with Perl internals, XS is often preferred.
• Extensive Use of C APIs: If you are working with a very extensive and performance-sensitive C API, XS might be necessary for optimal performance.
