Source

pub struct BatchAggregateLookupInfo {
    pub cache_key: String,
    pub outer_column_lower: String,

Expand description

Pre-computed info for batch aggregate lookups to avoid per-row allocations.

Fields§

§cache_key: String

The cache key for the batch aggregate results

§outer_column_lower: String

The outer column name (lowercase) to look up in outer_row

§outer_qualified_lower: Option<String>

Optional qualified outer column name (e.g., “u.id”)

§is_count: bool

Whether this is a COUNT expression (returns 0 for missing keys)
