I used to have friends, touch grass and even go outside. Rust has freed me from all these obligations and difficulties in life

In short these two are the same:

type T1<'a> = Box<dyn Bar<'a>>;
type T2<'a> = Box<dyn Bar<'a> + 'a>;

So by returning the type alias we are not returning Box<dyn Trait<'a>> but Box<dyn Trait<'a> + 'a>.

At an initial glance it seems like both functions should compile, after all the only difference is that we are returning an alias, right?

SPOILER AHEAD:

So why does the function returning an alias work while the other one doesn't?

The answer can be found here:

Fickle lifetimes Fickle lifetimes. GitHub Gist: instantly share code, notes, and snippets.

Oh Rust, you be fickle sometimes!

Today during a live stream I was exploring a lifetime issue, and I came up with this:

I got fed up with animating code for videos so I wrote Mimic. It plays back code based on simple instructions.

It's when the coding aspect is less fun it becomes a problem (in this case I find it easier to let my self be distracted instead of solving the two difficult problems ahead of me)
But yes, you are right.

Seems sensible! I find it's way to easy to let a whole Sunday go down the drain from consuming too much YouTube and such.

Doing the focus challenge for the next five days.
