Crate polyc_query_model 

DataFusion-free vocabulary for the versioned Query protocol.

This crate contains only semantic requests and result frames.

The REQUEST grants no scope. It names no realm, namespace, partition, table, source, or object. The Query service derives every one of those facts from the credential it verifies at its own boundary.

The TERMINAL FRAME is the opposite by design. It carries State’s complete source evidence, so SourceSnapshot transitively reaches State’s manifest and object vocabulary: projection keys, source checkpoints, object descriptors, and namespaces. That evidence flows from the server to the caller and grants the caller nothing. Do not read the small re-export list below as a small type graph.

Modules

evidence

The query protocol’s own closed source-evidence vocabulary.

Structs

DataFrame

One ordered Arrow IPC data frame.

QueryRequest

A version-independent semantic Query request.

RequestedBounds

Caller-requested ceilings. A deployment may only narrow them.

SchemaFrame

One Arrow IPC schema frame.

TerminalFrame

Final audited result facts.

Enums

Consistency

Projection consistency requested by a caller.

ErrorClass

Who is responsible for a query that did not succeed.

ModelError

Semantic request validation failure.

Parameter

One request parameter from the protocol’s closed vocabulary.

QueryOutcome

How a query ended, as the durable audit recorded it.

ResultFrame

One version-independent result stream frame.

Truncation

Whether a result carries every matching row.

Constants

MAX_FRAME_BYTES

Largest caller-requested result frame.

MAX_PARAMETERS

Largest number of positional parameters in one request.

MAX_PARAMETER_BYTES

Largest total UTF-8 parameter payload in one request.

MAX_RESULT_BYTES

Largest caller-requested released result size.

MAX_ROWS

Largest caller-requested result row count.

MAX_SQL_BYTES

Largest UTF-8 SQL statement accepted by the semantic boundary.

MAX_TIMEOUT

Largest caller-requested execution duration.

PROTOCOL_VERSION

The only protocol version this build speaks.
