pub struct Serializer;
Expand description

Serializer whose output is a Value.

This is the serializer that backs serde_json::to_value. Unlike the main serde_json serializer which goes from some serializable value of type T to JSON text, this one goes from T to serde_json::Value.

The to_value function is implementable as:

use serde::Serialize;
use serde_json::{Error, Value};

pub fn to_value<T>(input: T) -> Result<Value, Error>
where
    T: Serialize,
{
    input.serialize(serde_json::value::Serializer)
}

Trait Implementations

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. Read more
