🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Visits all items in the crate in some deterministic (but unspecified) order. If you just need to process every item, but don't care about nesting, this method is the best choice.

If you do care about nesting -- usually because your algorithm follows lexical scoping rules -- then you want a different approach. You should override visit_nested_item in your visitor and then call intravisit::walk_crate instead.
