Struct Options 

pub struct Options {
    pub prefix: String,
    pub origin: Option<String>,
}

How variable names become config paths.

Fields

prefix: String

Selects which variables to mount, and is stripped from the path. Required by load: mounting the whole environment would pull in PATH, HOME and whatever secrets happen to be set (spec F1.1). parse_dotenv allows it to be empty, a .env file being a closed set the caller chose deliberately.

origin: Option<String>

Source name for error messages.
