Struct PredicateWire 

pub struct PredicateWire {
    pub nodes: Vec<PredicateNodeWire>,
    pub root_idx: u32,
}

Wire format for Predicate. Flat node table with index references for And/Or/Not children.

Phase 5 of CAPABILITY_ENHANCEMENTS_PLAN.md. Crosses the nRPC envelope as serde-encoded bytes (postcard for cross-binding, JSON for debug fixtures); the substrate’s capability announcement path is unchanged.

Build via Predicate::to_wire; rebuild via PredicateWire::into_predicate.

Fields

nodes: Vec<PredicateNodeWire>

Flat node table. Children always live at lower indices than their parents.

root_idx: u32

Index of the root node within nodes. Always nodes.len() - 1 for a freshly-emitted to_wire() output; callers receiving an externally-built wire payload should not assume that.

Implementations

impl PredicateWire

pub fn into_predicate(self) -> Result<Predicate, PredicateWireError>

Rebuild a Predicate AST from the flat wire format.

Validates structural integrity: empty tables, out-of-bounds indices, and child-index cycles are surfaced as typed PredicateWireError rather than panicking. A successful rebuild is byte-equal to the input of the matching Predicate::to_wire call.

Trait Implementations

impl Clone for PredicateWire

fn clone(&self) -> PredicateWire

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PredicateWire

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PredicateWire

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PredicateWire

fn eq(&self, other: &PredicateWire) -> 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 PredicateWire

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
