An contract type is the type denoted by the name of an contract item.

A value of a given contract type carries the contract's public interface as attribute functions. A new contract value can be created by either casting an address to a contract type or by creating a new contract using the type attribute functions create or create2.

Example:

contract Foo {
    pub fn get_my_num() -> u256 {
        return 42
    }
}

contract FooFactory {
    pub fn create2_foo(mut ctx: Context) -> address {
        // `0` is the value being sent and `52` is the address salt
        let foo: Foo = Foo.create2(ctx, 0, 52)
        return address(foo)
    }
}
