Handle errors in init

[Nikhilesh Susarla]

I have an init func in a package. 

Inside the init function, I have a database initialization which returns error. How can I handle that error failure incase if it fails in the init function.

Thank you

Nikhilesh

You likely shouldn't do that in the init function, but do it from main, where you have a clearly defined error handling path.

There are ~four things you can do with an error in init:

1. Ignore it

2. Log it

3. Store it in a package-scoped variable and check that later

4. Panic

Neither of these are good options, but they are the only ones you have.
