Enum Kind 

pub enum Kind {
    Bool,
    Int {
        min: i64,
        max: i64,
    },
    Enum {
        choices: Vec<String>,
    },
    String {
        non_empty: bool,
    },
    Url,
    Path,
    SocketAddr,
    List {
        item: Box<Kind>,
    },
    Secret,
}

The type of a setting’s value, and so what it accepts.

Variants

Bool

true/false, also written on/off.

Int

An integer within min..=max.

Fields

min: i64

Smallest accepted value.

max: i64

Largest accepted value.

Enum

One of a fixed set of strings.

Fields

choices: Vec<String>

The accepted strings.

String

Free text.

Fields

non_empty: bool

Reject the empty string.

Url

An http or https URL.

Path

A filesystem path.

SocketAddr

A host:port socket address.

List

A list of items of one kind.

Fields

item: Box<Kind>

The kind of every item.

Secret

A credential: device-scope, never read back, never taken from text on a command line.
