Protobuf and Nanopb

The optional schema defines stable table.v1.Curve and table.v1.Map snapshots. Applications can import those messages into a larger protocol without treating native descriptors or arrays as wire formats.

import "table/v1/table.proto";

message CalibrationShare {
  table.v1.Map ignition_map = 1;
}

Embedded Nanopb

The Nanopb adapter encodes immutable views and decodes into separate caller-owned staging arrays. Validate a complete staged snapshot before replacing the active calibration so malformed or truncated data cannot produce a partial update.

Nanopb .options control generated storage and callbacks only. Application configuration owns labels, units, precision, display limits, and access rules.

Rust Prost support

Enable the prost feature to expose generated messages under table::proto::v1. Converting a message into a typed owner verifies scalar metadata, value families, ranges, dimensions, finite values, and native Table invariants before returning the active value.

See the Rust Protobuf API and the embedded integration sequence.
