Struct FromInto 

pub struct FromInto<U>(/* private fields */);

Converts from and into another type.

The value is deserialized as U and converted with Into and it’s serialized by cloning it and converting it into U. The value is optional if the converted value is, which means that with #[deser(skip_serializing_optionals)] the value is cloned and converted once more to find out.

        Rgb(value.0, value.1, value.2)
    }
}

where T: Send, U: Deserialize<'de> + Into<T> + 'static,

fn deserialize_into<'out>( out: &'out mut Option<T>, state: &mut State, ) -> SinkHandle<'out, 'de>

Creates a sink that deserializes the value into the given slot.

fn expecting() -> Cow<'static, str>

Returns what the value expects, for error messages.

fn initial_value() -> Option<T>

fn deserialize_atom( slot: &mut Slot<T, Self>, atom: Atom<'_>, state: &mut State, ) -> Result<(), Error>

Deserializes an atom into the slot.

fn deserialize_borrowed_atom( slot: &mut Slot<T, Self>, atom: Atom<'de>, state: &mut State, ) -> Result<(), Error>

Deserializes an atom that borrows from the data being deserialized into the slot.

fn finish(value: &T, state: &mut State) -> Result<(), Error>

Invoked after the serialization finished.

fn describe(value: &T, d: &mut dyn Describe)

Describes the Rust shape of the value.

fn container_shape(value: &T) -> ContainerShape

Returns the shape of the value if it’s a map or sequence.
