#[repr(transparent)]pub struct TableId(_);
Expand description
An opaque unique ID for a Table
within a World
.
Can be used with Tables::get
to fetch the corresponding
table.
Each Archetype
always points to a table via Archetype::table_id
.
Multiple archetypes can point to the same table so long as the components
stored in the table are identical, but do not share the same sparse set
components.
