Feature request: Automatically convert String to &str when required. #17300
Description
Please consider automatically converting Strings to string slices when a string is passed into a string slice context. Please pardon my total lack of experience with rust but I think this shouldn't introduce any bugs in the program since a string slice is a more restricted type than a String. Any thoughts?
Example:
fn takes_slice(slice: &str) {
println!("Got: {}", slice);
}
fn main() {
let s = "Hello".to_string();
takes_slice(s);
}
instead of ...
fn main() {
let s = "Hello".to_string();
takes_slice(s.as_slice());
}
May be we can provide a conversion operator like C++ does?
