suggestion: .rev().next()

[bojanserafimov]

What it does

Suggest .next_back() insteaad of .rev().next() when that's equivalent.

Lint Name

iter_rev_next

Category

pedantic

Advantage

People will point it out at code review anyway. Might as well spare them some typing

Drawbacks

I haven't thought about edge cases where applying the suggestion would not be correct

Example

foo.iter().rev().next()

Could be written as:

foo.iter().next_back()

[KisaragiEffective]

This is applicable when the type of foo.iter() is DoubleEndedIterator: both rev and next_back requires it as a bound.
