Detailed Description
--------------------

Types and utilities for building remote data loader manifests.

Use :ref:`exhale_class_classfoxglove_1_1data__provider_1_1ChannelSet` to declare channels, then construct a :ref:`exhale_struct_structfoxglove_1_1data__provider_1_1StreamedSource` with the resulting topics and schemas.

This header requires nlohmann/json and tobiaslocker/base64 to be available on the include path.




Example
#include<:ref:`file_foxglove_include_foxglove_data_provider.hpp`>
#include<foxglove/schemas.hpp>

namespacedp=:ref:`namespace_foxglove__data_provider`;

dp::ChannelSetchannels;
channels.insert<:ref:`exhale_struct_structfoxglove_1_1schemas_1_1Vector3`>("/demo");

dp::StreamedSourcesource;
source.url="/v1/data?flightId=ABC123";
source.id="flight-v1-ABC123";
source.topics=std::move(channels.topics);
source.schemas=std::move(channels.schemas);
source.start_time="2024-01-01T00:00:00Z";
source.end_time="2024-01-02T00:00:00Z";

dp::Manifestmanifest;
manifest.name="FlightABC123";
manifest.sources={std::move(source)};

std::stringjson_str=dp::to_json_string(manifest);
