Struct ruma::DeviceId

#[repr(transparent)]
pub struct DeviceId(_);

A Matrix key ID.

Device identifiers in Matrix are completely opaque character sequences. This type is provided simply for its semantic value.

Example

use ruma_common::{device_id, DeviceId, OwnedDeviceId};

let random_id = DeviceId::new();
assert_eq!(random_id.as_str().len(), 8);

let static_id = device_id!("01234567");
assert_eq!(static_id.as_str(), "01234567");

let ref_id: &DeviceId = "abcdefghi".into();
assert_eq!(ref_id.as_str(), "abcdefghi");

let owned_id: OwnedDeviceId = "ijklmnop".into();
assert_eq!(owned_id.as_str(), "ijklmnop");
