Expand description
An object-safe equivalent of Serde’s Deserializer
trait.
Any implementation of Serde’s Deserializer
can be converted to a
&dyn erased_serde::Deserializer
or Box<dyn erased_serde::Deserializer>
trait object using erased_serde::Deserializer::erase
.
use erased_serde::Deserializer;
use std::collections::BTreeMap as Map;
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::Deserializer::from_slice(JSON);
let cbor = &mut serde_cbor::Deserializer::from_slice(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<dyn Deserializer>> = Map::new();
formats.insert("json", Box::new(<dyn Deserializer>::erase(json)));
formats.insert("cbor", Box::new(<dyn Deserializer>::erase(cbor)));
// Pick a Deserializer out of the formats map.
let format = formats.get_mut("json").unwrap();
let data: Map<String, usize> = erased_serde::deserialize(format).unwrap();
println!("{}", data["A"] + data["B"]);
}
This trait is sealed and can only be implemented via a
serde::Deserializer<'de>
impl.
