holoscan::data_loggers::AsyncConsoleBackend | Holoscan SDK Documentation

Specialized backend for AsyncConsoleLogger that uses SimpleTextSerializer.

This backend provides the same console logging functionality as BasicConsoleLogger but works with the dual-queue async architecture. It uses SimpleTextSerializer for data serialization and provides formatted console output.

serialize_data_content

std::string holoscan::data_loggers::AsyncConsoleBackend::serialize_data_content(
    const DataEntry &entry,
    std::optional<cudaStream_t> stream = std::nullopt
) const
