Enum Origin 

pub enum Origin {
    Default,
    File {
        path: PathBuf,
    },
    Environment {
        variable: String,
    },
    Flag {
        flag: String,
    },
}

Where one setting’s value came from.

This is what makes precedence provable rather than asserted: config show renders it per setting, so a user sees the same answer a test does.

Variants

Default

Nothing set it; this is the built-in value.

File

A configuration document, and which one.

Fields

path: PathBuf

The document that set it.

Environment

The process environment, and which variable.

Fields

variable: String

The variable that set it.

Flag

The command line, and which flag.

Fields

flag: String

The flag that set it, as a user typed it.
