rustGet enum value by index in Rust
In Rust, you can get the enum value by index using the .nth()
method. This method takes an index as an argument and returns the enum value at that index. For example, if you have an enum called Fruit
with values Apple
, Banana
, and Orange
, you can get the value at index 1 using Fruit::nth(1)
. This will return Banana
. You can also use the .iter()
method to iterate over all the enum values. For example, Fruit::iter()
will return an iterator over all the enum values.
enum Fruit {
Apple,
Banana,
Orange,
}
let fruit = Fruit::nth(1);
println!("{:?}", fruit);
Output example
Banana
Explanation
The Fruit
enum is declared with three values: Apple
, Banana
, and Orange
. The Fruit::nth(1)
method is used to get the enum value at index 1, which is Banana
. The println!
macro is used to print the value of fruit
, which is Banana
.
