I'm trying to implement a simple text editor using the termion crate. When the user presses Backspace, I'd like to erase a single character - but I can't figure out how to achieve that.

The crate seems to only offer these options:

First of all I am new to Linux and Rust.

What I am trying to achieve is to print the timestamp to the terminal whenever a user execute a command in the terminal.

I have written a Rust program which will print the current timestamp on the right extreme of the terminal. I was planning to execute this program as systemd service in the background using a bash script. What this bash script does is inside an infinite loop, check the key press and if it is Enter, then execute the rust program. Before I execute the real Rust program, I just tried to echo a string. When I was running the service, I noticed that when I press Enter, echo runs many times before it stops. I also tried to execute the Rust program instead of the echo, but it didn't work the way I imagined. So my solution is wrong smewhere.

My question is, is my approach for this correct? I don't know whether running a background process with an infinite loop is good. This idea I took from the below video.

Creating systemd Service Files

This project is for educational purpose. I was inspired by the Powerline project and wanted to understand how it works and do something similar in small scale using Rust.

Could you guys let me know whether this approach is correct or point me to the right direction. Thanks

I am trying to get the user input after a certain duration by using two threads. A thread duration and thread for editing. When the thread duration completes,and that the thread for editing has not completed,the terminal state is not restored thus breaking the terminal. This happens when the user did not press "q" before the time duration

The only way of restoring the state of the terminal is to press"q" which will break the loop in the first thread calling droop on the termion raw terminal

I need to profile several variables like frames per second being rendered in my app. Therefore I need a simple way to update variables in the terminal.

I've searched and found ascii_table for generating tables, and termion for updating the terminal. But I suspect termion here is simply being used to clear the terminal.

Anyways, I was able to draw a simple table and update its contents every 200 miliseconds:
