GravityCapability

Struct GravityCapability 

Source
pub struct GravityCapability {
    pub enabled: bool,
    pub scope: TopologyScope,
    pub proximity: u8,
}
Expand description

Does this node participate in heat-driven migration, and within what topology / proximity bounds?

Same shape as GreedyCapability — gravity is a long-term drift policy that’s orthogonal to greedy’s per-event admission; the two flip independently.

Fields§

§enabled: bool

Does this node accept heat-driven migrations?

§scope: TopologyScope

Topology boundary gravity is allowed to migrate across.

§proximity: u8

Soft-preference weight, 0..=255. 0 disables gravity even when enabled = true.

Implementations§

Source§

impl GravityCapability

Source

pub fn write_into(self, caps: CapabilitySet) -> CapabilitySet

Write this projection back into a CapabilitySet as dataforts.gravity.* tags. Producer-side counterpart to Self::from_capability_set. Tag emission shape mirrors GreedyCapability::write_into.

Source

pub fn from_capability_set(caps: &CapabilitySet) -> Self

Read the projection from a CapabilitySet.
