Source of data for `ValueDeserializer`

## Variants§

§

### Deserializer

The deserializer used to actually deserialize a Value struct.

#### Fields

§`de: Deserializer<'gctx>`
§`definition: Definition`
§

### ConfigValue

A `ConfigValue`.

This is used for situations where you can’t address type via a TOML key, such as a value inside an array. The `ConfigSeqAccess` doesn’t know what type it should deserialize to so `ArrayItemDeserializer` needs to be able to handle all of them.

#### Fields

§`cv: ConfigValue`
§`key_path: &'err mut ArrayItemKeyPath`

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
