doctest dependencies don't seem to be taken into account

[nmattia]

I believe this is the case. In particular I have a crate with a doctest that uses serde_json:

/// ```
/// use serde_json;
/// ... (use serde_json here)

and cargo udeps reports the crate as not being used:

my_crate v0.1.0 (/path/to/my_crate)`
└─── (dev-)dependencies
     └─── "serde_json"

However cargo test (correctly) fails if I remove the crate.

(note: I'm running cargo udeps --all-targets).

Yes, it's a known issue:

cargo-udeps/src/lib.rs

Line 413 in 6e0b233

For example, `cargo-udeps` cannot detect usage of crates that are only used in doc-tests.",

Thanks for the quick response! Anything we can do about it?

#4 could solve it. But it's a larger project.
