Crate lance_select 

Row-selection primitives shared across Lance.

This crate contains:

• mask — RowAddrMask / NullableRowAddrMask and their underlying set types. These describe which rows survive a filter and are produced by scalar-index searches, prefilters, and the read planner.
• result — IndexExprResult / NullableIndexExprResult: the certainty-tagged wrappers around a RowAddrMask returned by a scalar- index expression evaluation, plus their boolean algebra (Not/BitAnd/BitOr).

These types were extracted from lance-core and lance-index so that consumers (benchmarks, downstream filtering code) can depend on the mask substrate without pulling in either of those larger crates.
