LGTM. There are some extra blank lines added (mostly before the if meets_msrv conditions.

Do you want to add the rest of the lints in this PR or split this up?

[suyashb95]

@flip1995 think I'll add all the lints in this one along with some instructions for introducing msrv for other lints. I'll run cargo dev fmt before I finish this up

[flip1995]

Great! Please ping me, when you're done, so I don't miss it

[suyashb95]

@flip1995 could you please review these changes?

[flip1995]

LGTM, but something is going on with manual_strip

[flip1995]

Thanks! Can you squash some of the commits, please? There are 3 or 4 formatting commits.
