pub(crate) fn refusal_next(body: &str) -> Option<String>Expand description
The next line out of a node’s structured rejection.
Every rejection body carries code, error and next (see
ERRORS.md), and next is the only one of the three that says what
to do. Printing the body alone left it as the fourth field of a JSON
object, which is where a reader who is already stuck stops reading.
