It's late so it's entirely possible I'm missing something very obvious, but what is going on with this trait impl conflict error?
trait Trait {
type Assoc;
}
struct TraitWrapper<T>(T);
struct TraitWrapperAssoc<T: Trait>(T::Assoc);
impl<T: Trait> Trait for TraitWrapper<T> {
type Assoc = TraitWrapperAssoc<T>;
}
impl<T: Trait> From<T::Assoc> for TraitWrapperAssoc<T> {
fn from(value: T::Assoc) -> TraitWrapperAssoc<T> {
TraitWrapperAssoc(value)
}
}
error[E0119]: conflicting implementations of trait `From<TraitWrapperAssoc<_>>` for type `TraitWrapperAssoc<_>`
--> src/lib.rs:12:1

12 | impl<T: Trait> From<T::Assoc> for TraitWrapperAssoc<T> {
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

= note: conflicting implementation in crate `core`:
- impl<T> From<T> for T;
For more information about this error, try `rustc --explain E0119`.
TraitWrapperAssoc<T> is not the same type as T::Assoc, right? So why would the from impl conflict with the blanket impl?
