codegen unit | when we produce LLVM IR, we group the Rust code into a number of codegen units. Each of these units is processed by LLVM independently from one another, enabling parallelism. They are also the unit of incremental re-use. codegen unit | when we produce LLVM IR, we group the Rust code into a number of codegen units.

Having both soundness and completeness is very hard, and usually soundness is more important. (see "soundness"). completeness | completeness is a technical term in type theory.
