Hello,

I'm trying to create a streaming/lending iterator trait with a for_each method but there are issues with lifetimes when the implementer of the trait isn't 'static (e.g. if it contains a reference with a non 'static lifetime).

Is there any way to make this example work and/or some insight into why it isn't possible?

Alternative playground for an alternative error.

I feel this should probably be filed as an issue, but haven't really made headway beyond that.

@quinedot thanks for the alternative error which gives some additional information!

I went ahead and filed an issue for this using the playground you posted.
