Enum vboxhelper::vmid::VmId

pub enum VmId {
    Name(String),
    Uuid(Uuid),
}

Identify a virtual machine.

The identifier can be created using the FromStr trait which will first attempt to parse the input parameters as an uuid, and fallback to treat it as a name.

use vboxhelper::vmid::VmId;

// will be treated as an VmId::Uuid
let mid1 = "00112233-4455-6677-8899-aabbccddeeff".parse::<VmId>();
if let Ok(VmId::Uuid(_)) = mid1 {
} else {
  panic!("Not an UUID!");
}

// will be treated as an VmId::Name
let mid2 = "myvim".parse::<VmId>();
if let Ok(VmId::Name(_)) = mid2 {
} else {
  panic!("Not a name!");
}

Variants

Name(String)

Using a name is more human-friendly than an Uuid, but it’s not universally unique.

Uuid(Uuid)

The uuid is (supposed to be) univeraslly unique, but a little cumbersome to memorize or type out.
