pub const BUILTIN: BuiltinDefinition;Expand description
The standard module automatically available to every supplied source module.
Use builtin. to qualify prelude types, traits and interpreter functions explicitly, or refer to those names without an import. Primitive types, pi and callback-only entity/time/tick bindings do not use this qualifier.
builtin is reserved. Its definitions ship inside Rust; it does not fetch code, resolve package versions, or grant device permissions.
