@arora-aman I think there are a few things we want to change. Mainly wording

src/types/closure.md

src/types/closure.md

+
+Regardless of if the data will be read by the closure, i.e. in case of wild card patterns, if a variable defined outside the closure is mentioned within the closure the variable will be captured in its entirety.
+
+## Other traits difference


I think we can actually delete this section. This is because the modified rules stated "the captured values" and we already clarified in the earlier Edition2018 subsection that the values captured are variables that are captured in its entirety

I'm fine removing it

-}
+### Capturing references in move contexts
+
+Rust doesn't allow moving fields out references as a result in the case of move closures, when the closure takes ownership of a path, it will only take ownership of a prefix of path that runs up until the first dereference (this may be the entire path if there are no dereferences in the path).


moving fields out of

Instead of truncate ... we reborrow the data being accessed throw the reference

This should be the other form of its.

Remove incorrect apostrophe

Expand on Unicode identifiers.

The phrase 'may not' could mean 'might not' or 'is not allowed to'.

The original sentence could mean that "its destructor is run" and "it is dropped" are two separate possibilities, rather than two names for the same action.

It is not clear if the original intended to mean these as two separate concepts, or synonyms for the same thing.
