| In-band lifetimes cannot be mixed with explicit lifetime binders. |
This is really just a re-phrasing of the error, it'd be great to elaborate a little - something like "a function/struct/whatever can either have explicit lifetime binders or in-band lifetimes".
| For example: | ||
|
|
||
| ``` | ||
| fn foo<'a, 'b>(x: &'a u32, y: &'b u32) {} // ok! |

I'd also add another example where only in-band lifetimes are used (with a short sentence before each example explaining how they differ).
