rust armanriazi type wraper
To create a Rust type wrapper, you can define a struct that wraps the desired type. This struct can then implement methods and traits to provide additional functionality or enforce certain constraints on the wrapped type. Here's an example:
struct TypeWrapper<T> {
value: T,
}
impl<T> TypeWrapper<T> {
fn new(value: T) -> Self {
TypeWrapper { value }
}
fn get(&self) -> &T {
&self.value
}
fn set(&mut self, value: T) {
self.value = value;
}
}
In the example above, TypeWrapper
is a generic struct that takes a type T
as a parameter. It has a field value
of type T
. The new
method is used to create a new instance of TypeWrapper
, and the get
and set
methods are provided to access and modify the wrapped value.
You can use the type wrapper as follows:
fn main() {
let mut wrapper = TypeWrapper::new(42);
println!("Value: {}", wrapper.get()); // Output: Value: 42
wrapper.set(100);
println!("Value: {}", wrapper.get()); // Output: Value: 100
}
In the example above, we create a TypeWrapper
instance with an initial value of 42
. We then print the value using the get
method. After that, we change the value using the set
method and print it again.
This is a basic example of creating a type wrapper in Rust. Depending on your specific requirements, you can add more methods and implement additional traits as needed.
