impl<const MODULUS: u64> PartialEq<U64Field<MODULUS>> for U64Field<MODULUS>

fn eq(&self, other: &U64Field<MODULUS>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
