Struct ODCSExporter 

pub struct ODCSExporter;

Exporter for ODCS (Open Data Contract Standard) v3.1.0 YAML format.

Implementations

impl ODCSExporter

pub fn export_table(table: &Table, _format: &str) -> String

Export a table to ODCS v3.1.0 YAML format.

Note: Only ODCS v3.1.0 format is supported. Legacy formats have been removed.

Arguments

• table - The table to export
• _format - Format parameter (ignored, always uses ODCS v3.1.0)

Returns

A YAML string in ODCS v3.1.0 format.

Example

use data_modelling_core::export::odcs::ODCSExporter;
use data_modelling_core::models::{Table, Column};

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

let yaml = ODCSExporter::export_table(&table, "odcs_v3_1_0");
assert!(yaml.contains("apiVersion: v3.1.0"));
assert!(yaml.contains("kind: DataContract"));

pub fn export_contract(contract: &ODCSContract) -> String

Export an ODCSContract directly to YAML format.

This is the preferred v2 API that directly serializes an ODCSContract struct, preserving all metadata and nested structures without reconstruction.

Arguments

• contract - The ODCSContract to export

Returns

A YAML string in ODCS v3.1.0 format.

Example

use data_modelling_core::export::odcs::ODCSExporter;
use data_modelling_core::models::odcs::{ODCSContract, SchemaObject, Property};

let contract = ODCSContract {
    api_version: "v3.1.0".to_string(),
    kind: "DataContract".to_string(),
    id: "my-contract-id".to_string(),
    name: "My Contract".to_string(),
    version: "1.0.0".to_string(),
    status: Some("active".to_string()),
    schema: vec![SchemaObject {
        name: "users".to_string(),
        properties: vec![Property {
            name: "id".to_string(),
            logical_type: "integer".to_string(),
            physical_type: Some("BIGINT".to_string()),
            required: true,
            primary_key: true,
            ..Default::default()
        }],
        ..Default::default()
    }],
    ..Default::default()
};

let yaml = ODCSExporter::export_contract(&contract);
assert!(yaml.contains("apiVersion: v3.1.0"));
assert!(yaml.contains("kind: DataContract"));

pub fn export_contract_validated( contract: &ODCSContract, ) -> Result<String, ExportError>

Export an ODCSContract to YAML with validation.

Similar to export_contract() but returns a Result for error handling.

Arguments

• contract - The ODCSContract to export

Returns

A Result containing the YAML string or an ExportError.

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

Export tables to ODCS v3.1.0 YAML format (SDK interface).

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

Export a data model to ODCS v3.1.0 YAML format (legacy method for compatibility).
