Struct ProtobufExporter 

pub struct ProtobufExporter;

Exporter for Protobuf format.

Implementations

impl ProtobufExporter

pub fn export(&self, tables: &[Table]) -> Result<ExportResult, ExportError>

Export tables to Protobuf format (SDK interface).

Arguments

• tables - Slice of tables to export

Returns

An ExportResult containing Protobuf .proto file content (proto3 by default).

Example

use data_modelling_core::export::protobuf::ProtobufExporter;
use data_modelling_core::models::{Table, Column};

let tables = vec![
    Table::new("User".to_string(), vec![Column::new("id".to_string(), "INT64".to_string())]),
];

let exporter = ProtobufExporter;
let result = exporter.export(&tables).unwrap();
assert_eq!(result.format, "protobuf");
assert!(result.content.contains("syntax = \"proto3\""));

pub fn export_with_version( &self, tables: &[Table], version: &str, ) -> Result<ExportResult, ExportError>

Export tables to Protobuf format with specified version.

Arguments

• tables - Slice of tables to export
• version - Protobuf syntax version (“proto2” or “proto3”)

Returns

An ExportResult containing Protobuf .proto file content.

pub fn export_table(table: &Table, field_number: &mut u32) -> String

Export a table to Protobuf message format.

Arguments

• table - The table to export
• field_number - Mutable reference to field number counter (incremented for each field)

Returns

A Protobuf message definition as a string.

Example

use data_modelling_core::export::protobuf::ProtobufExporter;
use data_modelling_core::models::{Table, Column};

let table = Table::new(
    "User".to_string(),
    vec![Column::new("id".to_string(), "INT64".to_string())],
);

let mut field_number = 0u32;
let proto = ProtobufExporter::export_table(&table, &mut field_number);
assert!(proto.contains("message User"));

Export a table to Protobuf message format (proto3 by default).

pub fn export_table_with_version( table: &Table, field_number: &mut u32, version: &str, ) -> String

Export a table to Protobuf message format with specified version.

pub fn export_model(model: &DataModel, table_ids: Option<&[Uuid]>) -> String

Export a data model to Protobuf format (legacy method for compatibility, proto3).
