Enum YamlConsumer 

pub enum YamlConsumer {
    Libyaml,
    Jsyaml,
    RYaml,
}

A real-world YAML parser whose accept/reject behavior Panache mirrors. These are distinct measured consumers, not interchangeable libyaml wrappers — see scripts/yaml-oracle/oracle.json and tests/yaml/consumer-matrix.md.

Variants

Libyaml

pandoc’s Haskell yaml (libyaml, ≈ YAML 1.1). Reads frontmatter. The lenient baseline: accepts duplicate keys (last value wins) and tabs in some positions.

Jsyaml

js-yaml (YAML 1.2). Reads Quarto frontmatter and hashpipe #| options. Rejects duplicate keys and tabs.

RYaml

R’s yaml package (libyaml-based), used by the RMarkdown toolchain — rmarkdown::yaml_front_matter for frontmatter and knitr for #| chunk options. Like libyaml but, measured against the suite, additionally REJECTS duplicate keys and tabs.

Trait Implementations

impl Clone for YamlConsumer

fn clone(&self) -> YamlConsumer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for YamlConsumer

impl Debug for YamlConsumer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for YamlConsumer

impl PartialEq for YamlConsumer

fn eq(&self, other: &YamlConsumer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
