sqlx_core::Transaction not re-exported in sqlx

[stadust]

Hi )/

Currently sqlx_core::Transaction isn't re-exported in sqlx. This means I cannot write out the return type of a function returning a connection acquired with ConnectionPool::begin

Since the struct is public in sqlx_core I could work around it by adding sqlx_core to my Cargo.toml but it'd be nice to have it re-exported directly in sqlx.

I came to say the same thing (and wow, only 8 minutes apart!) - it would be nice to have this type exported from sqlx :)

I could submit a PR for this if that's wanted? I'm afraid I'm not really familiar with github etiquette :(

Definitely wanted but @thedodd beat you to the PR: #114

Re: etiquette, personally I would have just made a PR for something small like this. Making an issue first (or asking on Discord) is more to save you from unneeded work. Either way, anyone ( including us ) are happy for your contribution in any form ( even just opening an issue saying "hey you missed this" ).
