FastCSV-Codegen

Ultra-Fast CSV Deserialization to Data Class based on Code Generations.

Uses osiegmar/FastCSV ^1.0.4 to parse CSV which is very fast! and to deserialize your CSV to Data Class it uses code generation via kapt (kotlin annotation processing).

The annotation is @CsvCodegen and it generates file with suffix of CsvCodegen, eg: PostCsvCodegen for you Post data class.
