QueryDenyRule

micromegas::analytics::lakehouse::query_deny_list

Struct QueryDenyRule 

Source 
pub struct QueryDenyRule {
    pub row: QueryDenyRow,
    /* private fields */
}
Expand description

A row compiled into one snapshot: the row, its planned expression, and the one piece of in-process state a rule accumulates. Lives only inside a DenySnapshot.

Fields§

§row: QueryDenyRow

Implementations§

Source§

impl QueryDenyRule

Source

pub fn new(row: QueryDenyRow, expr: Arc<dyn PhysicalExpr>) -> QueryDenyRule

pub so tests can build a rule directly from a compile_match_expr result, without going through Postgres – see QueryDenyList::with_snapshot.

Source

pub fn record_hit(&self)

Records that this rule matched a query, for the next QueryDenyList::refresh tick to flush into last_hit_at. Racing hits within one tick are fine – fetch_max keeps the most recent, and that’s all “is this rule still firing?” needs.
