Module retrieval

Module retrieval 

Source
Expand description

SQL retrieval argument binding and lowering to runtime-independent expressions.

Structs§

MultiStageEntry
RetrievalConstants

Enums§

AttentionSpec
RetrievalExpr
SQL-owned retrieval algebra. Physical scorers, fusers, closures, index choices and top-k strategies do not belong to this representation.
TextScoringMode

Traits§

RetrievalArguments
Runtime scalar evaluation and graph catalog access; SQL owns recursion and validation order.

Functions§

lower_operator_join_table_function
lower_sql_function_bound
lower_where
Lower representable SQL predicates using the supplied constant evaluator. Unsupported scalar shapes remain relational predicates.
lower_where_bound

Type Aliases§

ConstantEvaluator
Evaluates a scalar with the caller’s parameter values and without runtime function hooks.
