Enum QueryResponse 

pub enum QueryResponse {
    Stats {
        active_connections: u64,
        events_processed: u64,
        journal_sequence: u64,
    },
    Position {
        account: AccountId,
        balances: [AccountBalance; 16],
        count: u8,
    },
    RequestSeqHwm {
        hwm: u64,
    },
}

1:1 query responses returned directly from Application::apply, bypassing the fan-out scratch vec. Routed through OutputPayload::QueryResponse so the response stage can translate them to the public wire format.

Kept separate from ExecutionReport to avoid inflating that enum’s size with the large Position balance array (392 B vs ~64 B).

Variants

Stats

Transport stats snapshot emitted in response to a QueryStats event. Internal — never journaled, never sent on the wire directly. The response stage translates this to ResponseKind::StatsHeader for the client.

Fields

active_connections: u64

events_processed: u64

journal_sequence: u64

Position

Account balance snapshot emitted in response to QueryPosition. Internal — translated to ResponseKind::PositionSnapshot on the wire. Fixed array sized for the maximum number of currencies per account; count reports how many entries are populated.

Fields

account: AccountId

balances: [AccountBalance; 16]

count: u8

RequestSeqHwm

Per-key request_seq HWM snapshot emitted in response to QueryRequestSeq. The engine returns the value its dedup gate has currently advanced to for the calling connection’s key; reconnecting clients should set their next outbound seq to hwm + 1 so subsequent requests bypass dedup. 0 for a key that has never authenticated before.

Fields

hwm: u64

Trait Implementations

impl Clone for QueryResponse

fn clone(&self) -> QueryResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryResponse

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

Formats the value using the given formatter.

impl PartialEq for QueryResponse

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