# HIR Debugging
|
|
|
|
Use the `-Z unpretty=hir` flag to produce a human-readable representation of the HIR.
|
|
For cargo projects this can be done with `cargo rustc -- -Z unpretty=hir`.
|
|
This output is useful when you need to see at a glance how your code was desugared and transformed
|
|
during AST lowering.
|
|
|
|
For a full `Debug` dump of the data in the HIR, use the `-Z unpretty=hir-tree` flag.
|
|
This may be useful when you need to see the full structure of the HIR from the perspective of the
|
|
compiler.
|
|
|
|
If you are trying to correlate `NodeId`s or `DefId`s with source code, the
|
|
`-Z unpretty=expanded,identified` flag may be useful.
