Trait for versioning support during deserialization

Use the derive feature to generate the implementation from #[derive(DeserializeVersioned)] and #[versions(...)] attribute.

Required methods

fn deserialize_versioned<D>(
    deserializer: D,
    _version_map: &'de VM
) -> Result<Self, Error<D::Error>> where
    D: Deserializer<'de>, 

Entry point for the versioned deserialization

Implement this method to specialize the deserialization for a particular type.

The default implementation ignore the versioning

fn next_element<S>(
    seq_access: &mut S,
    _version_map: &'de VM
) -> Result<Option<Self>, Error<S::Error>> where
    S: SeqAccess<'de>, 

Entry point for deserializing an element in a sequence

Implement this method to specialize the deserialization for a particular type.

The default implementation ignore the versioning

fn next_value<M>(
    map_access: &mut M,
    _version_map: &'de VM
) -> Result<Self, Error<M::Error>> where
    M: MapAccess<'de>, 

Entry point for deserializing the next map value

Implement this method to specialize the deserialization for a particular type.

The default implementation ignore the versioning

fn next_key<M>(
    map_access: &mut M,
    _version_map: &'de VM
) -> Result<Option<Self>, Error<M::Error>> where
    M: MapAccess<'de>, 

Entry point for deserializing the next key value

Implement this method to specialize the deserialization for a particular type.

The default implementation ignore the versioning

fn variant<E>(
    enum_access: E,
    _version_map: &'de VM
) -> Result<(Self, E::Variant), Error<E::Error>> where
    E: EnumAccess<'de>, 

Entry point for deserializing the next variant

Implement this method to specialize the deserialization for a particular type.

The default implementation ignore the versioning
