Per-payload placement decision produced by negotiation.

Either a PlacementClass was chosen (status then carries the resulting crate::PlacementOutcome equivalent — encoded here as a typed decision rather than a wire enum so the receipt stage can map it onto payload_receipts[].status), or no acceptable placement could be satisfied and the decision is Failed with the structured rejection list. Both variants carry the payload provenance observed during negotiation so receipt synthesis does not need to infer it from callback responses.

Variants

Chosen

A placement was chosen. payload_kind, byte_size, and content_digest are copied from the negotiated payload envelope. chosen is the routing PlacementClass that won; first_preference is true when the chosen placement was the first entry in acceptable_placements. rejected lists any earlier placements that failed before the chosen one was reached.

Fields

payload_id: String

payload_kind: String

byte_size: u64

content_digest: Option<String>

chosen: PlacementClass

first_preference: bool

rejected: Vec<PlacementRejection>

Failed

No acceptable placement was satisfiable. payload_kind, byte_size, and content_digest are copied from the negotiated payload envelope. failure_class is either FailureClass::PlacementUnavailable (no acceptable placement supported at all) or FailureClass::PayloadTooLarge (every otherwise-supported placement rejected the byte size).

Fields

payload_id: String

payload_kind: String

byte_size: u64

content_digest: Option<String>

failure_class: FailureClass

rejected: Vec<PlacementRejection>

Implementations

impl PayloadPlacementDecision

pub fn payload_id(&self) -> &str

pub fn is_failed(&self) -> bool

Trait Implementations

impl Clone for PayloadPlacementDecision

fn clone(&self) -> PayloadPlacementDecision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PayloadPlacementDecision

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

Formats the value using the given formatter.

impl PartialEq for PayloadPlacementDecision

fn eq(&self, other: &PayloadPlacementDecision) -> 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.
