rustdoc: Render HRTB correctly for bare functions The angle brackets were not rendered, so code like this: some_func: for<'a> fn(val: &'a i32) -> i32 would be rendered as: some_func: fn'a(val: &'a i32) -> i32 However, rendering with angle brackets is still invalid syntax: some_func: fn<'a>(val: &'a i32) -> i32 so now it renders correctly as: some_func: for<'a> fn(val: &'a i32) -> i32 ----- However, note that this code: some_trait: dyn for<'a> Trait<'a> will still render as: some_trait: dyn Trait<'a> which is not invalid syntax, but is still unclear. Unfortunately I think it's hard to fix that case because there isn't enough information in the `rustdoc::clean::Type` that this code operates on. Perhaps that case can be fixed in a later PR. 2020-12-12 13:33:45 -06:00			`#![crate_name = "foo"]`
