oid! macro assumes der_parser is in the current namespace about der-parser HOT 4 CLOSED

As far as I understand, this is not possible now (see discussion and links in rust-lang/rust#54363)
There seems to be a workaround in rust-lang/rust#54647 but I haven't tested it.

from der-parser.

Hack idea: make oid!() a macro-by-example in der_parser that just invoked something like _oid!($crate, $($args)*) and have the proc macro be _oid!(). Hopefully this will pass the crate path in correctly so the proc macro can then use it in the generated code.

Maybe this hack could be the solution...

        format!(
             "{{ 
                  use der_parser::oid;
                  use der_parser::oid::Oid;
                  // this will be the ret value
                  der_parser::oid::Oid::new(alloc::borrow::Cow::Borrowed(&{}))}}",
             s
         )

from der-parser.

I'm working on this, and will try to find a solution for 6.0.

Workaround: import the re-exported der-parser:

use x509_parser::der_parser;
let oid = der_parser::oid!{ 1.2.3.4 };
