rust armanazi trait where
In Rust, the trait
keyword is used to define a trait, which is similar to an interface in other programming languages. Traits define a set of methods that a type must implement in order to satisfy the trait's requirements. The where
keyword is used in Rust to specify additional constraints on generic types or associated types.
Here's an example of using the trait
keyword in Rust:
trait Printable {
fn print(&self);
}
struct MyStruct;
impl Printable for MyStruct {
fn print(&self) {
println!("Printing MyStruct");
}
}
fn main() {
let my_struct = MyStruct;
my_struct.print();
}
In this example, we define a trait called Printable
with a single method print()
. We then implement the Printable
trait for the MyStruct
struct. Finally, in the main()
function, we create an instance of MyStruct
and call the print()
method on it.
