Enum SecondaryEngineGraphSimplificationRequest 

#[non_exhaustive]
pub enum SecondaryEngineGraphSimplificationRequest {
    Continue,
    Restart,
}

What the secondary engine asks the hypergraph optimizer to do next.

Mirrors enum class SecondaryEngineGraphSimplificationRequest in mysql-server/sql/handler.h.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Continue

kContinue = 0: continue optimization with the current hypergraph.

Restart

kRestart = 1: restart hypergraph with the provided subgraph-pair count.
