Struct rustc_hir::intravisit::nested_filter::None
source · pub struct None(());
Expand description
Do not visit any nested things. When you add a new “non-nested” thing, you will want to audit such uses to see if they remain valid.
Use this if you are only walking some particular kind of tree (i.e., a type, or fn signature) and you don’t want to thread a HIR map around.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
