**Header:** `ClikaRT/graph/onnx_export.h`

A handler for one operator, in one export ([`OnnxExportOptions::handlers`](./OnnxExportOptions.md#handlers)): it replaces the library's ONNX form for the nodes of [`code`](./OnnxExportHandler.md#code). The operators it writes are its own choice: the export writes them as they are, and [`io::OnnxModel::compile`](../io/OnnxModel.md#compile) refuses one this library does not read. Scope: the library's own operators; a handler for `OpCode::Custom`, the one code every user-defined operator shares, is refused.
