Type of change

Please delete options that are not relevant.

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Checklist:

• I ran bellow commands using the latest version of rust nightly.
• I ran cargo clippy --all -- -D warnings just before my last commit and fixed any issue that was found.
• I ran cargo fmt just before my last commit.
• I ran cargo test just before my last commit and all tests passed.
• I added my algorithm to the corresponding mod.rs file within its own folder, and in any parent folder(s).
• I added my algorithm to DIRECTORY.md with the correct link.
• I checked COUNTRIBUTING.md and my code follows its guidelines.

Please make sure that if there is a test that takes too long to run ( > 300ms), you #[ignore] that or
try to optimize your code or make the test easier to run. We have this rule because we have hundreds of
tests to run; If each one of them took 300ms, we would have to wait for a long time.

Please fix cargo clippy. See how it's handled in other files

[mobley-trent]

Hello @siriak , it seems that I can only fix cargo clippy by adding #[warn(dead_code)] but I don't see this in the rest of the loss functions.

[siriak]

Please take a look at new errors. I think this may be because the name of module and function coincide, but it's just a guess. You should be able to fix this without #[warn(dead_code)]

[siriak]

Looks good, thanks!
