Types

type Diagnostic added in v1.7.3 

type Diagnostic struct {
	Code    string `json:"code"`

func (e *Engine) NodeByID(id string) (types.Node, bool)

NodeByID returns the node with the given ID string, if it exists.

func (*Engine) Path 

func (e *Engine) Path(fromLabel, toLabel string) string

Path finds the shortest directed path from nodeA to nodeB. Returns a human-readable string.

func (*Engine) RenderExplore added in v1.7.3 

func (e *Engine) RenderExplore(request string, limit int) string

RenderExplore resolves broad natural language to candidate graph subjects and cites only graph relationships as proof for the returned context.

func (*Engine) RenderLookup added in v1.7.1 

func (e *Engine) RenderLookup(term string, limit int) string

RenderLookup formats ranked candidates with enough metadata to pick an exact subject for follow-up structural graph queries.

func (*Engine) Route added in v1.4.0 

func (e *Engine) Route(input string) string

Route reports workspace-layer repo routing for a query.

func (*Engine) RunRequest added in v1.7.1 

func (e *Engine) RunRequest(req types.QueryRequest) (string, error)
