how to get text from a file and store it in a variable rust
To get text from a file and store it in a variable in Rust, you can use the std::fs
module to read the file and then store the contents in a String
variable. Here's an example:
use std::fs;
fn main() {
// Read the file contents into a String variable
let file_contents = fs::read_to_string("path/to/file.txt").expect("Failed to read file");
// Print the contents
println!("{}", file_contents);
}
In this example, replace "path/to/file.txt"
with the actual path to your file. The read_to_string
function reads the file contents and returns them as a Result<String, std::io::Error>
. We use the expect
method to handle any potential errors and print an error message if the file reading fails.
Please note that you need to handle potential errors when reading the file, such as the file not existing or not having the necessary permissions.
