    Rust String

    Rust devided string in two types: &str and String.


    Rust String(String Object)

    A string is encoded in a UTF-8 sequence. String object type is provided in Standard Library. A string is growable in size.It represent string values that are provided at runtime.


    Rust &str(String literal)

    &str is also known as a string slice. &str are set of characters, which are hardcoded into a variable.String literals are static by default.String literals are static duration of entire program.

    Rust &str Example

    fn main() {
       let s:&str = "Hello World";
       println!(" {} ",s);
    }
