How to turn off cargo doc test and compile for a specific package in Rust

[liufuyang]

Describe the problem you are trying to solve

I have some generated rs code (from grpc proto filles) and they are checked in with my normal rust code under src but in some sub modules. The issue is when doing cargo test the doc test will run and some of the generated rs have comments with some indentations and cargo doc test trying to compile them and failed.

For example cargo test will try to compile (and perhaps run these lines) show here.

The cargo output could be like:

---- src/google/google.bigtable.v2.rs - google::bigtable::v2::row_filter::Interleave::filters (line 268) stdout ----
error: expected one of `!`, `.`, `::`, `;`, `?`, `{`, `}`, or an operator, found `row`
 --> src/google/google.bigtable.v2.rs:269:7
  |
3 | input row
  |       ^^^ expected one of 8 possible tokens

error: aborting due to previous error

Couldn't compile the test.

I seem cannot find a way to exclude or ignore those generated rs for doc test (without manually changing them)?

Describe the solution you'd like

Perhaps allow some type of configuration in Cargo.toml or some ignore file like .cargo_test_ignore to specify some path or packages to ignore cargo doing doc test on those?

Does setting the doctest field to false work for you?

[liufuyang]

But that turns off doctest completely? I have other rs files, the ones I edited, having doc tests.
For example I have lib.rs as:

pub mod bigtable; // code there needs doc test
pub mod google;  // code there does not need doc test

I do not think that is currently possible. See issues rust-lang/rust#59867 and rust-lang/rust#63193.
