Module backend 

Backend-agnostic interface used by the shared HTTP handlers.

Both datapress-duckdb and datapress-datafusion implement Backend against their own dataset registry / store. The generic handlers in crate::handlers and the crate::server::serve helper then drive either backend through the same code path.

Structs

ArrowIpcChunkWriter

DatasetSummary

One entry in GET /api/datasets.

ReloadStats

Outcome of a successful Backend::reload.

Traits
