I have a function that received an enum with some data that I don’t know inside. How can I retrieve its single values? For ex:
pub enum Type1{
Original {
A: u32,
B: u32,
},
Plus {
A: u32,
C: u32,
},
}
let bp = Type1::Original { A: 3, B: 4 };
// I have received bp but I want to work with bp.A
// How can I print it for example?
println!("{}", bp.A);
// Gives me the error: error[E0609]: no field `A` on type `Type1`
>Solution :
You can use if let:
if let Type1::Original { A, B } = bp {
println!("{}", A);
}
