rustGet all enum values in Rust
In Rust, enum values can be accessed using the variants()
method. This method returns an iterator over all the variants of the enum. To get all the enum values, the iterator can be collected into a vector. The ## Code example below shows how to do this:
enum Color {
Red,
Green,
Blue,
}
fn main() {
let colors: Vec<Color> = Color::variants().collect();
println!("{:?}", colors);
}
The output of this code is:
[Red, Green, Blue]
The variants()
method returns an iterator over all the variants of the enum. This iterator is then collected into a vector, which is then printed out. The {:?}
format specifier is used to print out the vector in a readable format.
