Struct NodeSet2Import 

pub struct NodeSet2Import { /* private fields */ }

NodeSetImport implementation for dynamically loading NodeSet2 files at runtime. Note that structures must be loaded with a type loader. By default the type loader for the base types is registered, but if your NodeSet2 file uses custom types you will have to add an TypeLoader using NodeSet2Import::add_type_loader.

Implementations

impl NodeSet2Import

pub fn new( preferred_locale: &str, path: impl AsRef<Path>, dependent_namespaces: Vec<String>, ) -> Result<Self, LoadXmlError>

Create a new NodeSet2 importer. The dependent_namespaces array contains namespaces that this nodeset requires, in order, but that are not included in the nodeset file itself. It does not need to include the base namespace, but it may.

Example

NodeSet2Import::new(
    "en",
    "My.ISA95.Extension.NodeSet2.xml",
    // Since we depend on ISA95, we need to include the ISA95 namespace.
    // Typically, the NodeSet will reference ns=1 as ISA95, and ns=2 as its own
    // namespace, this will allow us to interpret ns=1 correctly. Without this,
    // we would panic when failing to look up ns=2.
    vec!["http://www.OPCFoundation.org/UA/2013/01/ISA95"]
)

pub fn new_str( preferred_locale: &str, nodeset: &str, dependent_namespaces: Vec<String>, ) -> Result<Self, LoadXmlError>

Create a new NodeSet2 importer from an already loaded NodeSet2.xml file.

See documentation of NodeSet2Import::new.

pub fn new_nodeset( preferred_locale: &str, nodeset: UANodeSet, dependent_namespaces: Vec<String>, ) -> Self

Create a new importer with a pre-loaded nodeset. The dependent_namespaces array contains namespaces that this nodeset requires, in order, but that are not included in the nodeset file itself. It does not need to include the base namespace, but it may.

pub fn add_type_loader(&mut self, loader: Arc<dyn TypeLoader>)

Add a type loader for importing types from XML.

Any custom variable Value must be supported by one of the added type loaders in order for the node set import to work.

Trait Implementations

impl NodeSetImport for NodeSet2Import

fn register_namespaces(&self, namespaces: &mut NodeSetNamespaceMapper<'_>)

Register all namespaces used by this importer in a node set map.

fn get_own_namespaces(&self) -> Vec<String>

Get a list of namespaces that this import owns. This must be a subset of the namespaces it uses, registered in register_namespaces

fn load<'a>( &'a self, namespaces: &'a NodeSetNamespaceMapper<'_>, ) -> Box<dyn Iterator<Item = ImportedItem> + 'a>

Create an iterator over items imported from the nodeset. This will usually be lazy.
