Implementations

impl UaClient

pub fn new() -> Self

pub async fn connect( &self, endpoint_url: &str, endpoint: Option<&EndpointInfo>, auth: &AuthSpec, ) -> Result<()>

pub async fn browse_path(&self, node_id: &NodeId) -> Result<String>

Build the OPC UA Part 4 Annex A.2 RelativePath text for node_id by walking inverse hierarchical references back to the Root folder.

pub async fn node_path(&self, node_id: &NodeId) -> Result<Vec<NodeId>>

Return the path of NodeIds from the topmost reachable ancestor (typically Root) down to and including node_id.

pub async fn resolve_browse_path(&self, text: &str) -> Result<NodeId>

Resolve a textual browse path like “/Objects/Server/ServerStatus” into the matching NodeId by walking hierarchical references from RootFolder. A leading “Root” segment is accepted as a no-op. Segments may be plain names (namespace 0) or “N:Name” for explicit namespaces.

pub async fn discover_endpoints( &self, endpoint_url: &str, ) -> Result<Vec<EndpointInfo>>

pub async fn disconnect(&self) -> Result<()>

pub async fn browse_children(&self, node_id: &NodeId) -> Result<Vec<TreeChild>>

pub async fn read_node_summary(&self, node_id: &NodeId) -> Result<NodeSummary>

pub async fn browse_references( &self, node_id: &NodeId, ) -> Result<Vec<ReferenceRow>>
