TextCodec class abstract

Core interface for all text codecs in the textcrypt package.

This abstract class defines the contract that all codecs must implement. Each codec provides encoding and decoding functionality for text transformation.

Example:

class MyCodec implements TextCodec {
  @override
  String encode(String input) {
    // Custom encoding logic
    return transformedInput;
  }

  @override
  String decode(String input) {
    // Custom decoding logic
    return originalInput;
  }
}
