Struct MathErasedV1 

pub struct MathErasedV1(pub Box<MathElemCst>);

An ast::MathElemCst behind a stream-erasing parse (see above).

Trait Implementations

impl Clone for MathErasedV1

fn clone(&self) -> MathErasedV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MathErasedV1

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

Formats the value using the given formatter.

impl Deref for MathErasedV1

where Box<MathElemCst>: Deref,

type Target = <Box<MathElemCst> as Deref>::Target

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Deref for MathErasedV1

where Box<MathElemCst>: Deref,

impl Parse<WithSpan<Token, Span>> for MathErasedV1

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 MathErasedV1

fn eq(&self, other: &MathErasedV1) -> bool

Equality operator ==.

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

Inequality operator !=.
