Description
I am getting a false positive error in "unresolved-import" when I try to import a struct generated by a proc-macro in a separate crate.
Is there a way to override the error and quiet it, or maybe it could just be fixed. In the source code, it is clear the devs are aware of the issue
// This currently results in false positives in the following cases:
// - `cfg_if!`-generated code in libstd (we don't load the sysroot correctly)
// - `core::arch` (we don't handle `#[path = "../<path>"]` correctly)
// - proc macros and/or proc macro generated code

Research direction
Use the reported separate-crate proc-macro import as the starting reproduction case, then inspect the unresolved-import implementation and the source comment listing proc-macro false positives. Done means the generated struct import no longer produces a false positive, or the issue documents a supported way to suppress it.
