tui-rs

tui-rs is a Rust library to build rich terminal user interfaces and dashboards. It is heavily inspired by the Javascript library blessed-contrib and the Go library termui.

The library itself supports two different backends to draw to the terminal. You can either choose from:

• termion
• rustbox

However, some features may only be available in one of the two.

The library is based on the principle of immediate rendering with intermediate buffers. This means that at each new frame you should build all widgets that are supposed to be part of the UI. While providing a great flexibility for rich and interactive UI, this may introduce overhead for highly dynamic content. So, the implementation try to minimize the number of ansi escapes sequences generated to draw the updated UI. In practice, given the speed of Rust the overhead rather comes from the terminal emulator than the library itself.

Moreover, the library does not provide any input handling nor any event system and you may rely on the previously cited libraries to achieve such features.

Widgets

The library comes with the following list of widgets:

• Block
• Gauge
• Sparkline
• Chart
• BarChart
