pub struct Serializer;
Expand description
Serializer whose output is a Value
.
This is the serializer that backs serde_yaml::to_value
.
Unlike the main serde_yaml serializer which goes from some serializable
value of type T
to YAML text, this one goes from T
to
serde_yaml::Value
.
The to_value
function is implementable as:
use serde::Serialize;
use serde_yaml::{Error, Value};
pub fn to_value<T>(input: T) -> Result<Value, Error>
where
T: Serialize,
{
input.serialize(serde_yaml::value::Serializer)
}
Trait Implementations§
source§impl Serializer for Serializer
impl Serializer for Serializer
source§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.source§type SerializeSeq = SerializeArray
