# Description
Further work towards the goal that we can make `Record`'s field private
and experiment with different internal representations
## Details
- Use inplace record iter in `nu-command/math/utils`
- Guarantee that existing allocation can be reused
- Use proper record iterators in `path join`
- Remove unnecesary hashmap in `path join`
- Should minimally reduce the overhead
- Unzip records in `nu-command`
- Refactor `query web` plugin to use record APIs
- Use `Record::into_values` for `values` command
- Use `Record::columns()` in `join` instead.
- Potential minor pessimisation
- Not the hot value path
- Use sane `Record` iters in example `Debug` impl
- Avoid layout assumption in `nu-cmd-extra/roll/mod`
- Potential minor pessimisation
- relegated to `extra`, changing the representation may otherwise break
this op.
- Use record api in `rotate`
- Minor risk that this surfaces some existing invalid behavior as panics
as we now validate column/value lengths
- `extra` so things are unstable
- Remove unnecessary references in `rotate`
- Bonus cleanup
# User-Facing Changes
None functional, minor potential differences in runtime. You win some,
you lose some.
