Struct HeaderStageTok 

pub struct HeaderStageTok {
    pub tok: Token,
    pub span: Span,
}

@stage: persistent / @stage: 0 / @stage: 1 header token (cst.rs’s Header::Stage). Hand-written like BinOpTok above: the three spellings are separate unit Token variants with no shared payload for a #[leaf(...)] derive to key off, so this matches any of them and keeps whichever one matched (needed for a lossless round-trip — Unparse replays exactly the token that was read).

Fields

tok: Token

span: Span

Trait Implementations

impl Clone for HeaderStageTok

fn clone(&self) -> HeaderStageTok

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderStageTok

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

Formats the value using the given formatter.

impl Parse<WithSpan<Token, Span>> for HeaderStageTok

type Error = ParseError<Span>

Every error must be convertible to the universal one, so a field’s failure can become the enclosing type’s failure with no per-field where-predicate. Stating it HERE rather than at each derived impl is what keeps it out of the obligation graph: a per-field <FieldTy as Parse<Atom>>::Error: Into<…> predicate re-creates a projection cycle on a recursive field (E0275), which decycle’s bound-peeling does not break.

fn parse_stream<S: ParseStream<Atom = Atom>>( stream: &mut S, ) -> Result<Self, Self::Error>

Parse from a reborrowable stream.

fn parse(stream: impl IntoParseStream<Atom = Atom>) -> Result<Self, Self::Error>

Parse from anything that can become a stream — String, TokenStream, an existing stream.

fn attempt(self) -> Attempt<Self>

Wrap this value in Attempt, the atomic-parse marker: parsing an Attempt<Self> parses Self but rewinds the stream on failure (it requires Atom: Clone). This is the value constructor; value.attempt() is sugar for Attempt(value).

impl PartialEq for HeaderStageTok

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

Equality operator ==.

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

Inequality operator !=.

impl Spanned for HeaderStageTok

type Span = Span

fn span(&self) -> Span

impl StructuralPartialEq for HeaderStageTok

impl Unparse<WithSpan<Token, Span>> for HeaderStageTok

fn unparse<S: Emitter<Atom>>(&self, sink: &mut S) -> Result<(), S::Error>
