The previous method, where a layer would be passed directly, required to pass a "no-op" layer when no custom layer was needed. This should have in theory worked, however having a no-op layer seems to change the way the tracing lib applies filters internally, leading to some debug!() being printed despite them being out of the minimum level for the filters. Note however that this behavior was very inconsistent, and e.g. some debug!() would get printed and some others wouldn't, for no apparent reason. |

The driver crate is effectively the "main" function for the rust
compiler. It orchestrates the compilation process and "knits together"
the code from the other crates within rustc. This crate itself does
not contain any of the "main logic" of the compiler (though it does
have some code related to pretty printing or other minor compiler
options).
For more information about how the driver works, see the rustc dev guide.
