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

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

extern crate serde_json;
extern crate serde_cbor;

use std::collections::BTreeMap as Map;

use erased_serde::Deserializer;

fn main() {
    static JSON: &'static [u8] = br#"{"A": 65, "B": 66}"#;
    static CBOR: &'static [u8] = &[162, 97, 65, 24, 65, 97, 66, 24, 66];

    // Construct some deserializers.
    let json = &mut serde_json::de::Deserializer::from_slice(JSON);
    let cbor = &mut serde_cbor::de::Deserializer::new(CBOR);

    // The values in this map are boxed trait objects, which is not possible
    // with the normal serde::Deserializer because of object safety.
    let mut formats: Map<&str, Box<Deserializer>> = Map::new();
    formats.insert("json", Box::new(Deserializer::erase(json)));
    formats.insert("cbor", Box::new(Deserializer::erase(cbor)));

    // Pick a Deserializer out of the formats map.
