+If you aren't sure if there's a `ParamEnv` in scope somewhere that can be used it can be worth opening a thread in the [`#t-compiler/help`][compiler_help] Zulip channel where someone may be able to point out where a `ParamEnv` can be acquired from.
Manually constructing a `ParamEnv` is typically only needed at the start of some kind of top level analysis (e.g. hir typeck or borrow checking). In such cases there are three ways it can be done:
- Calling the [`tcx.param_env(def_id)` query][param_env_query] which returns the environment associated with a given definition.
