Struct WarningSink 

pub struct WarningSink { /* private fields */ }

Internal accumulator used by parsers to record warnings.

Wraps a RefCell so the document-level accessor closures can pass &WarningSink to parsers without juggling exclusive references. Pushes are interior-mutable; the document’s parse_warnings() accessor reads from the same cell.

Implementations

impl WarningSink

pub fn new() -> Self

pub fn push(&self, w: ParseWarning)

Push a warning into the sink.

pub fn record( &self, phase: ParsePhase, location: Option<LocationHint>, severity: Severity, message: impl Into<String>, )

Convenience: build and push a warning with the given pieces.

pub fn borrow_slice(&self) -> Ref<'_, [ParseWarning]>

Borrow the underlying slice for read-only access. Held borrow blocks further pushes until dropped, but parsers rarely hold this — they only push.

Trait Implementations

impl Debug for WarningSink

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

Formats the value using the given formatter.

impl Default for WarningSink

fn default() -> WarningSink

Returns the “default value” for a type.
