Struct v9::id::RunList

pub struct RunList<M: TableMarker> { /* fields omitted */ }

Stores Ids with great efficiency. Runs are stored like a Range. (In the case of a single run, zero allocation is needed.) Non-contiguous Ids have the same memory overhead as a Vec.

If you are iterating over the rows in a table, it’s easiest to use the table’s Read, Write, or Edit decl_context!. Otherwise you will need to take &$table::Id or &mut $table::Id as an argument to the Kernel.
