Struct LengthTok 

pub struct LengthTok {
    pub value: f64,
    pub unit: String,
    pub span: Span,
}

A length constant such as 12pt (two payload fields, hand-written).

Fields

value: f64

unit: String

span: Span

Trait Implementations

impl Clone for LengthTok

fn clone(&self) -> LengthTok

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LengthTok

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

Formats the value using the given formatter.

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

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 LengthTok

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

Equality operator ==.

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

Inequality operator !=.

impl Spanned for LengthTok

type Span = Span

fn span(&self) -> Span

impl StructuralPartialEq for LengthTok

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

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