#[lang = "add"]pub trait Add<Rhs = Self> {

}
The addition operator +.
Note that Rhs is Self by default, but this is not mandatory. For example, std::time::SystemTime implements Add<Duration>, which permits operations of the form SystemTime = SystemTime + Duration.

impl<'_> Add<&'_ str> for String[src]
Implements the + operator for concatenating two strings.
This consumes the String on the left-hand side and re-uses its buffer (growing it if necessary). This is done to avoid allocating a new String and copying the entire contents on every operation, which would lead to O(n^2) running time when building an n-byte string by repeated concatenation.
The string on the right-hand side is only borrowed; its contents are copied into the returned String.
Concatenating two Strings takes the first by value and borrows the second:
let a = String::from("hello");
let b = String::from(" world");
let c = a + &b;
// `a` is moved and can no longer be used here.If you want to keep using the first String, you can clone it and append to the clone instead:
let a = String::from("hello");
let b = String::from(" world");
let c = a.clone() + &b;
// `a` is still valid here.Concatenating &str slices can be done by converting the first to a String:
let a = "hello"; let b = " world"; let c = a.to_string() + b;
