rustExample of struct of structs in Rust
Structs of structs in Rust are a way of nesting structs within each other. This allows for more complex data structures to be created.
Example code
struct Outer {
inner: Inner,
}
struct Inner {
data: i32,
}
fn main() {
let outer = Outer {
inner: Inner { data: 5 },
};
println!("The inner data is: {}", outer.inner.data);
}
Output example
The inner data is: 5
Code explanation
struct Outer
: This is the outer struct which contains an inner struct.struct Inner
: This is the inner struct which contains a data field.let outer = Outer { inner: Inner { data: 5 } }
: This creates an instance of the outer struct, with an instance of the inner struct inside it.println!("The inner data is: {}", outer.inner.data)
: This prints out the data field of the inner struct.
