Implementation Steps

1. Data Structures (structures.rs):

   • TimeStruct, SpectralData, SpectralInfo, OtherInfo, ImageInfo
   • Main IrisData container

2. Read Functions (read.rs):

   • Implement read_time, read_spectral_data, etc.
   • Use std::io::Read trait

3. Write Functions (write.rs):

   • Implement write_time, write_spectral_data, etc.
   • Use std::io::Write trait

4. Example Implementation (examples.rs):

   • Create sample data
   • Write/read roundtrip test

5. Main Integration (main.rs):

   • CLI interface
   • Example execution

Key Differences from C

• Pointers replaced with Vec types
• Automatic memory management
• Manual serialization instead of memory casting
• Comprehensive error handling with Result type
