Enum Value 

pub enum Value {
    Null,
    Bool(bool),
    Integer(i64),
    Float(f64),
    String(String),
    List(Vec<Value>),

Configuration value wrapper 配置值包装器

Equivalent to Spring’s @Value annotation support. 等价于Spring的@Value注解支持。

Can hold different types of values and convert between them. 可以保存不同类型的值并在它们之间转换。
