Subject: [PATCH] Workaround rust nightly borrowcheck error (#1860)
|
|
|
|
Surprisingly, this fixes the error filed at #1860!
|
|
|
|
This seems suspicious, perhaps indicative of a bug in Rust's non-lexical
|
|
lifetime handling?
|
|
|
|
The lifetimes in the `handlebars::Renderable::render` method signature
|
|
are quite complicated, and its unclear to me whether or not Rust is
|
|
catching some new safety edge-case that wasn't previously handled
|
|
correctly...
|
|
|
|
Possibly related to `drop` order, which I *think* is related to the
|
|
order of binding statements?
