Replace string using Regex in Rust
It’s way harder to begin working in Rust when compared to other programming languages for me.
For example we might want to find the certain regex “first: \d+”, which means the text has first: 200 for example, and replace that with the different value like first: 100.
In my case, after replace the text, I want to save that to file. How do we do that in Rust.
