Struct graph_rs_sdk::http::serde_yaml::Serializer

pub struct Serializer<W> { /* private fields */ }

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, 

pub fn new(writer: W) -> Serializer<W>

Creates a new YAML serializer.

pub fn into_inner(self) -> W

Unwrap the underlying io::Write object from the Serializer.

Trait Implementations

impl<'a, W> Serializer for &'a mut Serializer<W> where
    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.

type Error = Error

The error type when some error occurs during serialization.

Type returned from serialize_seq for serializing the content of the sequence.

type SerializeTuple = ThenWrite<'a, W, SerializeArray>

Type returned from serialize_tuple for serializing the content of the tuple.

type SerializeTupleStruct = ThenWrite<'a, W, SerializeArray>

Type returned from serialize_tuple_struct for serializing the content of the tuple struct.
