signet as Faraday middleware?

[sporkmonger]

With the switch to Faraday, it might make sense to offer signet as Faraday middleware rather than acting as a front-end to it. E.g.

client = Signet::OAuth2::Client.new...
access_token = ... # get access token

conn = Faraday.new do |builder|
  builder. user Signet::OAuth2::Client, access_token
end

conn.get(...)

(Copied from @sqrrrl's issue on the original Signet project.)

I created a middleware that'll do this for you

class CredentialsMiddleware < Faraday::Middleware
  def on_request(env)
    options[:client].apply! env.request_headers
  end
end

credentials = Google::Auth::Credentials.default
conn = Faraday.new(url: "...") do |c|
  c.use CredentialsMiddleware, client: credentials.client
end
