About

Issue #7187

Description

Removing custom PartialEq and Eq implementations helps avoid issues like:

warning: function pointer comparisons do not produce meaningful results since their addresses are not guaranteed to be unique
  --> src/uu/od/src/formatteriteminfo.rs:29:45
   |
29 |             (IntWriter(a), IntWriter(b)) => a == b,
   |                                             ^^^^^^
   |
   = note: the address of the same function can vary between different codegen units
   = note: furthermore, different functions could have the same address after being merged together

Observable on nightly 1.86

Thank you

Removing custom PartialEq and Eq implementations helps avoid issues like:

    help: refactor your code, or use `std::ptr::fn_addr_eq` to suppress the lint
