Method Next

graph/shape.go:13–13

Next advances the iterator to the next value, which will then be available through the Result method. It returns false if no further advancement is possible, or if an error was encountered during iteration. Err should be consulted to distinguish between the two cases.

(ctx context.Context)

	// error was encountered during iteration.  Err should be consulted to distinguish
	// between the two cases.
	Next(ctx context.Context) bool
}

// Index is an index lookup iterator. It allows to check if an index contains a specific value.
