Variants

Alias

An alias of an externally-defined item

Fields

alias: Alias

The original alias item

resolved: Cell<Option<GlobalItemIndex>>

Once the alias has been resolved, we set this to Some(target_gid) so that we can simply shortcut to the resolved target once known.

Constant(Constant)

A constant declaration in AST form

Type(TypeDecl)

A type or enum declaration in AST form

Procedure(RefCell<Box<Procedure>>)

Procedure symbols are wrapped in a RefCell to allow us to mutate the procedure body when linking any externally-defined symbols it contains.

Compiled(ItemInfo)

An already-assembled item
