Implementations

impl ExplaineeStatement

pub fn depends_on(&self) -> BTreeSet<GlobalId>

pub fn broken(&self) -> bool

Statements that have their broken flag set are expected to cause a panic in the optimizer code. In this case:

1. The optimizer pipeline execution will stop, but the panic will be intercepted and will not propagate to the caller. The partial optimizer trace collected until this point will be available.
2. The optimizer trace tracing subscriber will delegate regular tracing spans and events to the default subscriber.

This is useful when debugging queries that cause panics.
