func ConvertError ¶

func ConvertError(rerr error) *core.Error

ConvertError converts an error from Dang evaluation into a *core.Error, preserving GraphQL error extensions as error values.

func NewNestedClientMetadata ¶

func NewNestedClientMetadata(ctx context.Context) (*engine.ClientMetadata, error)

NewNestedClientMetadata returns fresh metadata for a nested client to evaluate Dang code under, in the caller's session.

func WithNestedClientServer ¶

func WithNestedClientServer(
	ctx context.Context,
	query *core.Query,
	nestedClientMetadata *engine.ClientMetadata,
	inertAttachables bool,
	fnCall *core.FunctionCall,
	moduleContext dagql.ObjectResult[*core.Module],
	fn func(ctx context.Context, gqlClient graphql.Client) ([]byte, error),
) ([]byte, error)

WithNestedClientServer serves the Dagger API for a nested client on a local listener and calls fn with a GraphQL client pointed at it. The server is shut down when fn returns; any error it hit while serving is returned. In-engine SDK clients pass inertAttachables to reject implicit access to the caller's host while still allowing graph values explicitly passed to them.

The nested client's parent is the client whose scope ctx holds, exactly as for container execs: workspace operations run under a scope other than the client their request metadata names, and the session only accepts a child registered by its held parent scope.
