Fix compiler error

[myclevorname]

When running cargo build on the current commit, I get this output.
compiler.log
When running cargo clippy, I get this output.
clippy.log

The relevant error is:

error: unnecessary qualification
  --> src/utils.rs:90:16
   |
90 |     let file = fs::File::open( input_path )?;
   |                ^^^^^^^^^^^^^^
   |
note: the lint level is defined here
  --> src/lib.rs:8:5
   |
8  |     unused_qualifications
   |     ^^^^^^^^^^^^^^^^^^^^^
help: remove the unnecessary path segments
   |
90 -     let file = fs::File::open( input_path )?;
90 +     let file = File::open( input_path )?;
   |

Applying said change results in a successful build, but there are still many warnings generated, but it builds, at least.
