Expand description

“Collection” is the process of determining the type and other external details of each item in Rust. Collection is specifically concerned with inter-procedural things – for example, for a function definition, collection will figure out the type and signature of the function, but it will not visit the body of the function in any way, nor examine type annotations on local variables (that’s the job of type checking).

Collecting is ultimately defined by a bundle of queries that inquire after various facts about the items in the crate (e.g., type_of, generics_of, predicates_of, etc). See the provide function for the full set.

At present, however, we do run collection across all items in the crate as a kind of pass. This should eventually be factored away.
