I'm trying to read a file into a string, but i get a compiler error with the message "error[E0599]: no method named read_to_string
found for struct File
in the current scope"
Can't understand what I'm doing wrong. Here's the offending code below:
impl Todo {
fn new() -> Result<Todo, std::io::Error> {
let mut content = String::new();
std::fs::OpenOptions::new()
.read(true)
.write(true)
.create(true)
.open("todo.txt")?
.read_to_string(&mut content)?
}
}
Versions: cargo: 1.56.0 rustc: 1.56.1 rustup: 1.24.3
In order to use the trait method read_to_string
, you have to bring Read
trait into the scope.
use std::io::Read;
