Struct ModelLoader 

pub struct ModelLoader<B: StorageBackend> { /* private fields */ }

Model loader that uses a storage backend

Implementations

impl<B: StorageBackend> ModelLoader<B>

pub fn new(storage: B) -> Self

Create a new model loader with the given storage backend

pub async fn load_model( &self, workspace_path: &str, ) -> Result<ModelLoadResult, StorageError>

Load a model from storage

For file-based backends (FileSystemStorageBackend, BrowserStorageBackend):

• Loads from tables/ subdirectory with YAML files
• Loads from relationships.yaml file

For API backend (ApiStorageBackend), use load_model_from_api() instead.

Returns the loaded model data and a list of orphaned relationships (relationships that reference non-existent tables).

pub async fn load_domains( &self, workspace_path: &str, ) -> Result<DomainLoadResult, StorageError>

Load all domains from storage

Scans the workspace for domain directories and loads each domain along with its associated ODCS tables, ODPS products, and CADS assets.

Domain directories are identified by the presence of a domain.yaml file.

pub async fn load_domains_from_list( &self, workspace_path: &str, domain_directory_names: &[String], ) -> Result<DomainLoadResult, StorageError>

Load domains from explicit domain directory names

This is more reliable than load_domains() when you know the domain directory names, as it doesn’t rely on directory discovery which may be limited by the storage backend.

pub async fn load_workspace( &self, workspace_path: &str, ) -> Result<Option<Workspace>, StorageError>

Load workspace configuration from workspace.yaml

Arguments

• workspace_path - Path to the workspace directory

Returns

The Workspace configuration if found, or None if workspace.yaml doesn’t exist

pub async fn save_workspace( &self, workspace_path: &str, workspace: &Workspace, ) -> Result<(), StorageError>

Save workspace configuration to workspace.yaml

Arguments

• workspace_path - Path to the workspace directory
• workspace - The Workspace configuration to save

pub async fn load_domain_config( &self, domain_dir: &str, ) -> Result<Option<DomainConfig>, StorageError>

Load domain configuration from domain.yaml

Arguments

• domain_dir - Path to the domain directory

Returns

The DomainConfig if found, or None if domain.yaml doesn’t exist

pub async fn save_domain_config( &self, domain_dir: &str, config: &DomainConfig, ) -> Result<(), StorageError>

Save domain configuration to domain.yaml

Arguments

• domain_dir - Path to the domain directory
• config - The DomainConfig to save

pub async fn load_domain_config_by_name( &self, workspace_path: &str, domain_name: &str, ) -> Result<Option<DomainConfig>, StorageError>

Load domain configuration by name from a workspace

Arguments

• workspace_path - Path to the workspace directory
• domain_name - Name of the domain (folder name)

Returns

The DomainConfig if found

pub async fn get_domain_id( &self, domain_dir: &str, ) -> Result<Option<Uuid>, StorageError>

Get domain ID from domain.yaml, or None if not found

This is a helper method used by BPMN/DMN/OpenAPI loaders to get the domain ID.

Arguments

• domain_dir - Path to the domain directory

Returns

The domain UUID if found in domain.yaml, or None

pub async fn load_all_domain_configs( &self, workspace_path: &str, ) -> Result<Vec<DomainConfig>, StorageError>

Load all domain configurations from a workspace

Arguments

• workspace_path - Path to the workspace directory

Returns

A vector of all DomainConfig found in the workspace
