Do all generic types implement the Copy trait?


Do all generic types in Rust implement the Copy trait? To expand upon this, are there a lot of types in the standard library that implement this trait, other than that of generic types?
Do all generic types in Rust contain the Copy trait?
No. That's why you have to explicitly request that a generic type implement Copy:
fn foo<T>(value: T)
where T: Copy,
{
// ...
}
are there a lot of types in the standard library that implement this trait,
See for yourself. A trait's documentation lists its known implementors.
