`bson::Uuid` does not implement `Eq`, cannot be used as a key in a `HashMap`

[remkop22]

Hi,

I wish to use bson::Uuid as a key in a HashMap. Currently this is not possible because it only implements PartialEq and not Eq. Is there any specific reason that limits implementing Eq for this type? uuid::Uuid does implement Eq so for me it would make sense if it reproduces the same interface.

Many Thanks!

Thanks for filing this issue! You're correct that there isn't any meaningful reason why bson::Uuid doesn't implement Hash or Eq, and in fact the next release (2.2.0) will add implementations for those traits (see #345). In the meantime, you can start using the latest beta release (2.2.0-beta.1) to get that functionality today.
