Enum tor_persist::Futureproof

source · [−]

pub enum Futureproof<T> {
    Understandable(T),
    Unknown(JsonValue),
}

Expand description

A wrapper type for types whose representation may change in future versions of Arti.

This uses #[serde(untagged)] to attempt deserializing as a type T first, and falls back to a generic JSON value representation if that fails.

Variants

`Understandable(T)`

A successfully-deserialized T.

`Unknown(JsonValue)`

A generic JSON value, representing a failure to deserialize a T.
