Support unexported fields #198

Open kuritka opened 2 years ago

kuritka commented 2 years ago

I decided to extend the functionality to support unexported fields. I have one main reason for this.

After I load a structure from envvars, I want to perform the steps that further create the state. I load several variables and then calculate a new one from them, but there is no reason to have the originals public. Another example is that I parse the value of an enum from a private string variable. etc...
```
// ENV_LOG_LEVEL=info
// my.strLogLevel is unexported and loaded from ENV_LOG_LEVEL
// exported my.LogLevel is NOT string and calculated from unexported one
my.LogLevel = parseLogLevel(my.strLogLevel) 
```
