💛 - Coveralls

[anirudh2]

Lots of interesting changes! Nice work! A lot of my requests are just for documenting public functions

[anirudh2]

Few small things left

[anirudh2]

Reiterating this request! Just with all extensions empty.

Thanks, Gustavo!

Why not use into_iter() here to get rid of deref in *address?

[pedrohba1]

Shoudnt it log when allocation is not found, or either the same for SignedReceiptorDeploymentId`?, for example

// adding this to the end of the ifs
         else {
            tracing::warn!("No allocation found for deployment: {:?}", deployment_id);
        }
    } else {
        tracing::warn!("Neither SignedReceipt nor DeploymentId was found in request extensions.");
    }
