UX Dataflow

API Docs Crates.io Code coverage Tests MPL-2.0 licensed Gitter chat loc

UX Dataflow is a streaming capable data multiplexer that allows you to aggregate data and then process it using a Chain of Responsibility design pattern.

UX Dataflow was originally an attempt to implement a DataTable-like structure from Python's powerful data analysis library - Pandas.

But during the development process, it became clear that a data processing mechanism was needed that would allow data to be extended by adding new data channels and the ability to handle asynchronous data streams.

UX Dataflow is part of the Angular Rust framework.

Angular Rust is a high productivity, platform-agnostic frontend framework for the Rust language. It now supports desktop and web development. Angular Rust currently uses Clutter for desktop development and WebAssembly for web development. We are planning to add support for mobile development.

Angular Rust structure


  • DataFrame abstraction for extending data-feeds (channels)
  • Metadata describing DataStream channels
  • Streaming capability
  • Composite data channel support.
  • Support for heterogeneous data links such as dataset of OHLCV, f64, i64 and U256 in the same DataStream.

The unimplemented features depend on User-Experience during the development of the UX Indicators crate. So far, we have implemented the features required for the UX Charts crate.

Quick Start

Install UX Dataflow:

cargo add ux-dataflow
