False positives for the syn crate

[niklasf]

It looks like syn is particularly tricky. Looking at https://github.com/dtolnay/syn/search?p=1&q=unsafe&unscoped_q=unsafe I think there should be fewer real uses of unsafe:

Functions  Expressions  Impls  Traits  Methods  Dependency
0          25           1      0       2        ☢         └── syn v0.14.2

Thank you for the report!

It looks like the Impl and Methods metrics are accurate.

The Expressions are probably too high since tests and examples are included, but the "unsafe" string literals and comments are not included. cargo-geiger make use of the same crate, syn, for parsing .rs files.

Ah, thank you. Then this is just a duplicate of #3.
