Struct GravityCapability 

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

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

impl GravityCapability

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.

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

Read the projection from a CapabilitySet.

Trait Implementations

impl Clone for GravityCapability

fn clone(&self) -> GravityCapability

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for GravityCapability

impl Debug for GravityCapability

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for GravityCapability

fn default() -> GravityCapability

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for GravityCapability

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for GravityCapability

impl PartialEq for GravityCapability

fn eq(&self, other: &GravityCapability) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for GravityCapability

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
