Struct BackendKind 

pub struct BackendKind {
    pub id: String,
    pub isolation: IsolationClass,
    pub persistent_volumes: bool,
    pub scale_to_zero: bool,
}

A backend a node offers, with the capabilities the scheduler gates placement on: the isolation class it provides, plus whether it can back persistent volumes and scale a workload to zero. Populated from the backend’s Capabilities at node advertisement.

Fields

id: String

Backend id ("vmm", …).

isolation: IsolationClass

Isolation class this backend provides on this node.

persistent_volumes: bool

Whether this backend can attach the spec’s persistent volumes. A spec with volumes placed on a false backend would run storage-less (silent data loss), so the scheduler treats it as ineligible.

scale_to_zero: bool

Whether this backend can scale a workload to zero. A scale_to_zero spec on a false backend would run always-on (a silently missed cost optimization), so the scheduler treats it as ineligible rather than surprise the operator.
