False positive on Rust code

I have the following snippet of code in my project:
```rust
    files: &mut [file::File],
```
`tagref check` yields:
```
Error when validating [file::File] @ ./src/plan.rs:68: No such file or directory (os error 2)
```
It would be nice to be able to disable tagref on a given line for cases like this.

**Environment information:**
 - Tagref version: 1.10.0
 - OS: nixos
