An object-safe equivalent of Serde's Serializer trait.

Any implementation of Serde's Serializer can be converted to an &erased_serde::Serializer or Box<erased_serde::Serializer> trait object using erased_serde::Serializer::erase.

    // Construct some serializers.
    let json = &mut serde_json::ser::Serializer::new(io::stdout());
    let cbor = &mut serde_cbor::ser::Serializer::new(io::stdout());

    // The values in this map are boxed trait objects. Ordinarily this would not
    // be possible with serde::Serializer because of object safety, but type
    // erasure makes it possible with erased_serde::Serializer.
    let mut formats: Map<&str, Box<Serializer>> = Map::new();
    formats.insert("json", Box::new(Serializer::erase(json)));
    formats.insert("cbor", Box::new(Serializer::erase(cbor)));

    // These are boxed trait objects as well. Same thing here - type erasure
    // makes this possible.
    let mut values: Map<&str, Box<Serialize>> = Map::new();
    values.insert("vec", Box::new(vec!["a", "b"]));
    values.insert("int", Box::new(65536));

    // Pick a Serializer out of the formats map.
    let format = formats.get_mut("json").unwrap();

    let value = values.get("vec").unwrap();

impl<'a> Serializer for &'a mut (Serializer + Send + Sync)

type Ok = Ok

The output type produced by this Serializer during successful serialization. Most serializers that produce text or binary output should set Ok = () and serialize into an [io::Write] or buffer contained within the Serializer instance. Serializers that build in-memory data structures may be simplified by using Ok to propagate the data structure around.

The error type when some error occurs during serialization.
