This glo Term | Meaning ------------------------|-------- AST | the abstract syntax tree produced by the syntax crate; reflects user syntax very closely. -DAG | a directed acyclic graph is used during compilation to index which queries execute which other queries. ([see more](incremental-compilation.html)) 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. cx | we tend to use "cx" as an abbrevation for context. See also `tcx`, `infcx`, etc. +DAG | a directed acyclic graph is used during compilation to keep track of dependencies between queries. ([see more](incremental-compilation.html)) DefId | an index identifying a definition (see `librustc/hir/def_id.rs`). Uniquely identifies a `DefPath`. HIR | the High-level IR, created by lowering and desugaring the AST ([see more](hir.html)) HirId | identifies a particular node in the HIR by combining a def-id with an "intra-definition offset".
