1 /// This declares a list of types which can be allocated by `Arena`.
3 /// The `few` modifier will cause allocation to use the shared arena and recording the destructor.
4 /// This is faster and more memory efficient if there's only a few allocations of the type.
5 /// Leaving `few` out will cause the type to get its own dedicated `TypedArena` which is
6 /// faster and more memory efficient if there is lots of allocations.
8 /// Specifying the `decode` modifier will add decode impls for `&T` and `&[T]` where `T` is the type
9 /// listed. These impls will appear in the implement_ty_decoder! macro.
