Move bounds on associated types to the type Given `trait X { type U; }` the bound `<Self as X>::U` now lives on the type, rather than the trait. This is feature gated on `feature(generic_associated_types)` for now until more testing can be done. The also enabled type-generic associated types since we no longer need "implies bounds". 2020-06-11 15:50:34 +00:00			`--> $DIR/issue-38091.rs:1:12`

Avoid cycles from projection bounds Only check the own predicates of associated types when confirming projection candidates. Also consider implied bounds when comparing trait and impl methods. 2020-07-25 12:41:53 +00:00			For more information about this error, try `rustc --explain E0277`.
