Struct yaml_rust_davvid::emitter::YamlEmitter

pub struct YamlEmitter<'a> { /* fields omitted */ }

Implementations

impl<'a> YamlEmitter<'a>

pub fn new(writer: &'a mut dyn Write) -> YamlEmitter<'_>

pub fn compact(&mut self, compact: bool)

Set ‘compact inline notation’ on or off, as described for block sequences and mappings.

In this form, blocks cannot have any properties (such as anchors or tags), which should be OK, because this emitter doesn’t (currently) emit those anyways.

pub fn is_compact(&self) -> bool

Determine if this emitter is using ‘compact inline notation’.

pub fn multiline_strings(&mut self, multiline_strings: bool)

Render strings containing multiple lines in literal style.

Examples

use yaml_rust_davvid::{Yaml, YamlEmitter, YamlLoader};

let input = r#"{foo: "bar!\nbar!", baz: 42}"#;
let parsed = YamlLoader::load_from_str(input).unwrap();
eprintln!("{:?}", parsed);

let mut output = String::new();
let mut emitter = YamlEmitter::new(&mut output);
emitter.multiline_strings(true);
emitter.dump(&parsed[0]).unwrap();

assert_eq!(output.as_str(), "\
---
foo: |
  bar!
  bar!
baz: 42");

pub fn is_multiline_strings(&self) -> bool

Determine if this emitter will emit multiline strings when appropriate.

pub fn dump(&mut self, doc: &Yaml) -> EmitResult
