AttachmentUploadState class sealed

Represents the upload state of an attachment.

This sealed class provides a type-safe way to represent the different states an attachment can be in during the upload process. Each state provides relevant information for that stage of the upload.

Example usage:

switch (uploadState) {
  case UploadStatePreparing():
    // Show preparing indicator
  case UploadStateInProgress(:final uploaded, :final total):
    // Show progress: uploaded/total
  case UploadStateSuccess():
    // Show success state
  case UploadStateFailed(:final error):
    // Show error: error.toString()
}
