pub struct QueryEngine<'a> { /* private fields */ }

Expand description

Query engine for traceability operations.

Implementations§

Source §

impl<'a> QueryEngine<'a>

Source

pub fn new(graph: &'a KnowledgeGraph) -> Self

Creates a new query engine.

Source

pub fn lookup(&self, id: &str) -> LookupResult<'a>

Looks up an item by ID.

If the item is not found, returns suggestions for similar IDs.

Source

pub fn trace_upstream( &self, id: &ItemId, options: &TraversalOptions, ) -> Option<TraversalResult>

Queries the upstream traceability chain for an item.

Source

pub fn trace_downstream( &self, id: &ItemId, options: &TraversalOptions, ) -> Option<TraversalResult>

Queries the downstream traceability chain for an item.

Source

pub fn get(&self, id: &ItemId) -> Option<&'a Item>

Gets an item by ID.

Source

pub fn items_by_type(&self, item_type: ItemType) -> Vec<&'a Item>

Gets all items by type.

Source

pub fn graph(&self) -> &'a KnowledgeGraph

Returns the graph reference.
