Apache DataFusion Protobuf Models

Apache DataFusion is an extensible query execution framework, written in Rust, that uses Apache Arrow as its in-memory format.

This crate contains the prost-generated Rust types for DataFusion's logical and physical plan protobuf schemas. It is intentionally kept narrow: it has no DataFusion dependencies beyond datafusion-proto-common and exposes only the generated structs (and optional pbjson/serde support).

This crate is consumed by datafusion-proto and may also be depended on directly by other DataFusion crates that need to refer to the proto schema types without pulling in the full datafusion-proto surface.

Most projects should use the datafusion-proto crate directly, which re-exports this module. If you are already using the datafusion-proto crate, there is no reason to use this crate directly in your project as well.
