Traits

CollectAndApply

Imagine you have a function F: FnOnce(&[T]) -> R, plus an iterator iter that produces T items. You could combine them with f(&iter.collect::<Vec<_>>()), but this requires allocating memory for the Vec.

Interner

The central trait in the shared abstraction layer, specifying all implementation-specific details for rustc and rust-analyzer.

LiftInto

An interner whose associated types can be lifted into another interner J.
