Struct serde_yaml::Serializer [−][src]
A structure for serializing Rust values into YAML.
Example
use anyhow::Result; use serde::Serialize; use std::collections::BTreeMap; fn main() -> Result<()> { let mut buffer = Vec::new(); let mut ser = serde_yaml::Serializer::new(&mut buffer); let mut object = BTreeMap::new(); object.insert("k", 107); object.serialize(&mut ser)?; object.insert("J", 74); object.serialize(&mut ser)?; assert_eq!(buffer, b"---\nk: 107\n...\n---\nJ: 74\nk: 107\n"); Ok(()) }
Implementations
impl<W> Serializer<W> where
W: Write,
[src]
W: Write,
pub fn new(writer: W) -> Self
[src]
Creates a new YAML serializer.
pub fn into_inner(self) -> W
[src]
Unwrap the underlying io::Write
object from the Serializer
.

[src]
W: Write,
type Ok = ()
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
type Error = Error
The error type when some error occurs during serialization.
type SerializeSeq = ThenWrite<'a, W, SerializeArray>
Type returned from serialize_seq
for serializing the content of the
sequence. Read more

Type returned from serialize_tuple
for serializing the content of
the tuple. Read more
type SerializeTupleStruct = ThenWrite<'a, W, SerializeArray>
