Michael Goulet bc60d50eaa Provide associated type information in method chains ... When encountering an unmet obligation that affects a method chain, like in iterator chains where one of the links has the wrong associated type, we point at every method call and mention their evaluated associated type at that point to give context to the user of where expectations diverged from the code as written. ``` note: the expression is of type `Map<std::slice::Iter<'_, {integer}>, [closure@$DIR/invalid-iterator-chain.rs:12:18: 12:21]>` --> $DIR/invalid-iterator-chain.rs:12:14 | LL | vec![0, 1] | ---------- this expression has type `Vec<{integer}>` LL | .iter() | ------ associated type `std::iter::Iterator::Item` is `&{integer}` here LL | .map(|x| { x; }) | ^^^^^^^^^^^^^^^ associated type `std::iter::Iterator::Item` is `()` here ```		2022-12-11 09:46:01 -08:00
