Implement "standard" map/collection methods

[Jon Gjengset]

This issue tracks the implementation status of various "standard" methods on collections in general and maps in particular that should be added to flurry. Checked boxes have already been "claimed".

• drain (hard) and IntoIterator (easy) for both owned and & (see #33)

If you want to pick up any of these, leave a comment here and/or open a draft PR!

I would like to implement Eq, Index and clear.

[Jon Gjengset]

@Stupremee How about you do Eq and Index first, and then we do clear in a separate PR afterwards?

[Daniel Sanchez]

I think I can try to implement the Clone one . Is it ok?

[Jon Gjengset]

Absolutely, it's all yours!

[Justus K]

I will also implement Debug since Index doesnt work atm

[Daniel Sanchez]

I think I can do with_hasher and with_capacity_and_hasher also. But I see them as checked already.

[Jon Gjengset]

@danielSanchezQ Those are already (accidentally) being added in #24

[soruh]

I'd like to take a crack at implementing reserve.

[Jon Gjengset]

@soruh all yours!

[Daniel Sanchez]

I can give a try to the retain method 😄

[soruh]

I took a quick look at drain and into_iter in #33, but I'm not sure how correct & efficient what I wrote actually is.

[soruh]

@jonhoo I'd appreciate it if you could mark the drain and IntoIter impls as open (maybe with a link to my existing work); I don't really have the time to look into this further at the moment (I'm still open for questions about my initial implementation #33). I'll write another comment if I have the time to work on this and no one already has.

[Jon Gjengset]

I'm replacing this with #62 now that there's just one item left.
