If you want to save the response from a function for later, you can use the std::fs::write
function to write the response to a file on your local file system.
For example, suppose you have a Rust function named my_function
that returns a String containing the response you want to save. You can use the following code to write the response to a file named response.txt
:
use std::fs;
fn my_function() -> String {
// function body goes here
}
fn main() {
let response = my_function();
fs::write("response.txt", response).expect("Failed to write response to file");
}
This will create a new file named response.txt
in the current directory, and write the response from the my_function
function to the file. If the file already exists, it will be overwritten with the new response.
You can then use the std::fs::read_to_string
function to read the saved response from the file at a later time:
use std::fs;
fn main() {
let response = fs::read_to_string("response.txt").expect("Failed to read response from file");
// use the response here
}
I hope this helps! Let me know if you have any other questions.
