rustHow to get enum value in Rust
To get an enum value in Rust, you can use the .into()
method. This method takes the enum variant and returns the associated value. For example, if you have an enum Fruit
with variants Apple
and Orange
, you can get the associated values with Fruit::Apple.into()
and Fruit::Orange.into()
. The output of this method will be the associated values of the enum variants.
enum Fruit {
Apple,
Orange,
}
let apple_value = Fruit::Apple.into();
let orange_value = Fruit::Orange.into();
println!("Apple value: {:?}", apple_value);
println!("Orange value: {:?}", orange_value);
Output example
Apple value: Apple
Orange value: Orange
Explanation
The .into()
method takes the enum variant and returns the associated value. In this example, Fruit::Apple.into()
returns the associated value of the Apple
variant, which is Apple
, and Fruit::Orange.into()
returns the associated value of the Orange
variant, which is Orange
.
