Struct mz_expr::explain::HumanizedNotice

source ·
pub struct HumanizedNotice(/* private fields */);
Expand description

A HumanizerMode that is ambiguous but allows us to print valid SQL statements, so it should be used in optimizer notices.

The inner parameter is true iff literals should be redacted.
