Struct serde_json::value::Serializer
source · [−]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
sourceimpl Serializer for Serializer
impl Serializer for Serializer
type Ok = Value
type Ok = Value
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
