Enum Value 

pub enum Value {
    Bool(bool),
    Int(isize),
    Float(f64),
    String(String),
    List(Vec<LocatedValue>),
    Map(Map),
    Null,
}

Dynamically typed configuration value.

The tree shape produced by parsing configuration input: booleans, integers, floats, strings, lists, maps, and null. Use the is_*/as_*/into_* family of methods to inspect or extract a specific variant without a match.

use tanzim_value::Value;

let value: Value = 8080isize.into();
assert!(value.is_int());
assert_eq!(value.as_int(), Some(8080));

let value: Value = "localhost".into();
assert_eq!(value.as_string().map(String::as_str), Some("localhost"));

Variants

Bool(bool)

A boolean value.

Int(isize)

A signed integer value.

Float(f64)

A floating-point value.

String(String)

A string value.

List(Vec<LocatedValue>)

A list of located values.

Map(Map)

A map of keys to located values.

Null

The absence of a value.
