move a json file in rust

To move a JSON file in Rust, we need to perform the following steps:

1. Open the existing file with the help of File::open() method.
2. Create or open the target location where you want to move the JSON file.
3. Move the JSON file to the target location using the fs::rename() method.
4. Handle any possible errors that may occur during the process.

Here's an example code snippet demonstrating how to move a JSON file in Rust:

main.rs
use std::fs;
use std::path::Path;

fn main() -> std::io::Result<()> {
    // open the existing JSON file
    let source_file = Path::new("path/to/existing/file.json");
    let file = fs::File::open(source_file)?;

    // set target location
    let target_dir = Path::new("path/to/target");
    let target_file = target_dir.join(source_file.file_name().unwrap());

    // move the JSON file to target location
    fs::rename(source_file, target_file)?;

    Ok(())
}

In this code, we first open the existing JSON file using the File::open() method. Then we set the target directory and create a new file path there using Path::join() method. Finally, we use the fs::rename() method to move the file to the target location.

Make sure to handle any possible errors that may occur during the process using the std::io::Result type.
