Expand description

Object containing all opened Tables in read-only mode.

This is an encapsulated object that contains all available Table’s in read-only mode.

It is a Sealed trait and is only implemented on a (tuple, containing, all, table, types, ...).

This is used to return a single object from functions like OpenTables::open_tables rather than the tuple containing the tables itself.

To replace tuple.0 style indexing, field_accessor_functions() are provided on this trait, which essentially map the object to fields containing the particular database table, for example:

let tables = open_tables();

// The accessor function `block_infos()` returns the field
// containing an open database table for `BlockInfos`.
let _ = tables.block_infos();
