Enum DebugSubscriptionUpdate 

pub enum DebugSubscriptionUpdate {
    Absent(DebugSubscriptionType),
    Present(DebugSubscriptionData),
}

A debug subscription type followed by prefixed optional matching data.

Absent writes the type and a false boolean. A Present value writes the payload’s type, a true boolean, and the matching payload. This representation cannot pair one subscription type with another type’s data.

Examples

use mcproto_types::{
    DebugSubscriptionData, DebugSubscriptionType, DebugSubscriptionUpdate, TypeCodec,
};

let absent = DebugSubscriptionUpdate::absent(DebugSubscriptionType::Bee);
let mut encoded = Vec::new();
absent.encode(&mut encoded)?;
assert_eq!(encoded, [0x01, 0x00]);
assert_eq!(DebugSubscriptionUpdate::decode(&mut encoded.as_slice())?, absent);

let present = DebugSubscriptionUpdate::present(
    DebugSubscriptionData::DedicatedServerTickTime,
);
let mut encoded = Vec::new();
present.encode(&mut encoded)?;
assert_eq!(encoded, [0x00, 0x01]);

See the official Debug Subscription Update documentation.

Variants

Absent(DebugSubscriptionType)

The selected subscription type has no following payload.

Present(DebugSubscriptionData)

The selected subscription type is followed by its payload.
