Struct Set 

pub struct Set(/* private fields */);

A virtual AST node for YAML sets (!!set tagged scalars)

Implementations

impl Set

pub fn cast(node: SyntaxNode<Lang>) -> Option<Self>

Cast a SyntaxNode to a Set only if it’s a TAGGED_NODE with !!set tag

pub fn members(&self) -> impl Iterator<Item = YamlNode> + '_

Iterate over the set members, preserving formatting.

Each member is yielded as a YamlNode wrapping the key content node (the scalar, mapping, or sequence that forms the set member). The iteration order follows the document order.

To compare members semantically (ignoring quoting style), use yaml_eq on the returned nodes.

Note: !!set entries appear in two CST layouts: explicit-key ? item (KEY/VALUE as direct MAPPING children) and implicit item: null (KEY/VALUE inside MAPPING_ENTRY). Both are handled.

pub fn len(&self) -> usize

Get the number of members in the set.

pub fn is_empty(&self) -> bool

Check if the set is empty.

pub fn contains(&self, value: impl AsYaml) -> bool

Check if the set contains a specific value.

Trait Implementations

impl Clone for Set

fn clone(&self) -> Set

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Set

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

Formats the value using the given formatter.

impl Hash for Set

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Set

fn eq(&self, other: &Set) -> 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.
