Expand description

Underlying kind of the configuration value.

Standard operations on a `Value` by users of this crate do not require knowledge of `ValueKind`. Introspection of underlying kind is only required when the configuration values are unstructured or do not have known types.

## Variants

### `Nil`

### `Boolean(bool)`

### `I64(i64)`

### `I128(i128)`

### `U64(u64)`

### `U128(u128)`

### `Float(f64)`

### `String(String)`

### `Table(Map<String, Value>)`

### `Array(Vec<Value>)`
