Expand description
System indices: table-level structure persisted as indices.
Unlike normal indices, whose internals stay opaque behind
crate::format::IndexMetadata::index_details, the table format genuinely
interprets the contents of these indices (fragment remapping, row
visibility). They therefore live at the table layer.
The Index-trait adapters for these structs live in lance-index, which
re-exports the structs defined here.
