Summary

Our DatabaseClient will fetch user tokens from DynamoDB. We need a struct to store the data pertaining to a token.

We use the chrono crate to handle date/time

Split new types out into new token module

Why you don't put [services] prefix in your revisions' names for the identity service? I thought we had a convention that we put a prefix depending on the "module" we work on. So, for instance, [web], [server], [native]. [services] Is at the same level, [identity] is deeper one level. Is there a particular reason you do not do this here? Has this rule changed?

What is the reason to use Option here? Why token is not optional and the rest of the fields are?

I have this pattern but I've actually never pushed it as a rule. The other day @jonringer-comm asked me if he should prefix his commit titles with [nix], so this is coming up in multiple places. Open to creating a rule for this but curious for other perspectives

I see. For me, personally, it would be handier because I set my herald rule to detect any revisions with [services] in their names. If you decide to user other naming then fine but I think it will be better for everybody to use one, consistent pattern.

As a side note, maybe we could use tags?

That is a really good point about Herald rules. @benschac was asking on ENG-1055 about whether we should come up with a new Herald rule, since we're no longer recommending subscribing to all diffs... this idea makes sense to me.

i'll use [services][identity] going forward. are herald rules case sensitive?

We use this struct to hold data returned from DynamoDB, so we need to handle incomplete data. I think token should actually be wrapped in an Option too... will fix

Rename Token to AccessToken to be more precise, make token field optional (to handle incomplete data in DynamoDB)

Accepting to preempt somebody adding me due to dependency change

Sorry, but I don't really understand.

  1. This seems to be inconsistent with https://phabricator.ashoat.com/D3573?vs=on&id=11131:
  2. where's userID?
  3. why do you use just auth_type? I don't see pakePasswordCiphertext/walletAddress.
  4. What's the primary key here?

  1. I was passing userID and deviceID to functions as separate args in addition to the Token struct, but perhaps that's confusing. I can include all of it in the Token struct.
  1. https://phabricator.ashoat.com/D3573?vs=on&id=11902#toc in a later revision than the one you linked I realized we didn't actually need to store that stuff in the token table
  1. primary key is the userID (partition key) + deviceID (sort key)

add userID and deviceID to AccessToken struct

Thanks, I think having args more explicit in the struct is more readable.
