Struct EventMeta 

pub struct EventMeta<'input> {
    pub anchor: Option<&'input str>,
    pub anchor_loc: Option<Span>,
    pub tag: Option<Cow<'input, str>>,
    pub tag_loc: Option<Span>,
}

Rare per-event fields for node-typed events (Scalar, SequenceStart, MappingStart).

Bundled behind Option<Box<EventMeta>> so that the common case — no anchor, no source-text tag — pays only one 8-byte pointer instead of ~96 bytes of inline storage. Events with tags and anchors are rare in block-heavy and Kubernetes YAML; boxing them moves the cost to the uncommon path.

Fields

anchor: Option<&'input str>

The anchor name, if any (e.g. &foo).

anchor_loc: Option<Span>

Source span of the &name anchor token — from & through the last byte of the name. Some when anchor is Some, None otherwise.

tag: Option<Cow<'input, str>>

The resolved tag, if any (e.g. "tag:yaml.org,2002:str" for !!str).

Verbatim tags (!<URI>) borrow from input. Shorthand tags resolved via %TAG directives or the built-in !! default produce owned strings.

tag_loc: Option<Span>

Source span of the tag token — from ! through the last byte of the tag token. Some when tag is Some, None otherwise.

Trait Implementations

impl<'input> Clone for EventMeta<'input>

fn clone(&self) -> EventMeta<'input>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'input> Debug for EventMeta<'input>

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

Formats the value using the given formatter.

impl<'input> PartialEq for EventMeta<'input>

fn eq(&self, other: &EventMeta<'input>) -> 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.
