SSE event types for Parquet streaming.

Variants

Start

Initial event with estimated totals.

Fields

total_estimate: usize

cache_key: String

Progress

Progress update.

Fields

processed: usize

total: usize

Batch

Batch of geometry data as base64-encoded Parquet.

Fields

data: String

Base64-encoded Parquet data containing this batch’s meshes.

mesh_count: usize

Number of meshes in this batch.

batch_number: usize

Batch sequence number (1-indexed).

vertex_base: Option<u32>

Cross-batch streams only (stream_shapes=cross-batch, #5407): the whole-stream index of this batch’s first vertex row. The mesh rows’ vertex_start is whole-stream too and may point below it, at a shape an earlier batch carried. ABSENT on every batch-local stream, which is how a client learns the server did not honour the opt-in and each batch decodes on its own.

index_base: Option<u32>

Companion of vertex_base, in indices (the unit of index_start), not index-table rows.

Complete

Processing complete.

Fields

stats: ProcessingStats

metadata: ModelMetadata

symbolic_data: SymbolicDataWithProvenance

2D symbol data extracted from IfcAnnotation and IfcGrid entities — parity with POST /api/v1/parse (issue #900).

Error

Error occurred.

Fields

message: String
