Struct NormalizedHello 

pub struct NormalizedHello {
    pub epoch: u64,
    pub comparator_version: u32,
    pub tables: Vec<TableWireSchema>,
    pub normalized_fp: u64,
}

The subscription handshake (§3), sent once before any NormalizedBatch. Slimmer than the flat Hello: flat per-table schemas, no nested view schema or per-level sort.

Fields

epoch: u64

comparator_version: u32

tables: Vec<TableWireSchema>

The base tables this subscription’s footprint can surface (the query’s table tree), in a stable order (sorted by name) so the wire form is deterministic.

normalized_fp: u64

FNV-1a-64 fingerprint over { table → (ordered columns, PK) } by name — a sibling of the engine’s schema_fp. Drift ⇒ re-subscribe.

Trait Implementations

impl Clone for NormalizedHello

fn clone(&self) -> NormalizedHello

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NormalizedHello

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NormalizedHello

fn deserialize<__D>( __deserializer: __D, ) -> Result<NormalizedHello, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for NormalizedHello

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for NormalizedHello
