Struct RecClauseV1 

pub struct RecClauseV1 {
    pub name: BindName,
    pub params: Vec<Param>,
    pub eq: DefEqTok,
    pub value: ExprErasedV1,
}

One name param* = value clause of a val rec/let rec group — upstream bind_value_nonrec (parser_v1.mly:459-465) as reached from bind_value_rec (:455-458). 0.1 deltas from crate::cst::ast::RecBinding: no : ty ascription and no multi-clause | patbot* = value sugar exist in 0.1 at all (bind_value_nonrec has neither a COLON ty nor a BAR alternative — 0.0.6’s recdecargpart machinery has no 0.1 counterpart), so there are no ascription/leading_bar/extra fields to mirror. params is upstream’s list(param_unit) (see super::Param’s doc comment), reaching PatBot through the same cross-root DAG edge cst::ast::RecBinding.params makes (cst.rs:753-762); value goes through super::ExprErasedV1 (not Box<Expr>) so this struct never joins Expr’s SCC — byte-for-byte cst.rs’s own RecBinding.value: ExprErased discipline.

Trait Implementations

impl Clone for RecClauseV1

fn clone(&self) -> RecClauseV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecClauseV1

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

Formats the value using the given formatter.

impl<__SyanMacro_Atom> Parse<__SyanMacro_Atom> for RecClauseV1

where __SyanMacro_Atom: Spanned + Clone, BindName: Parse<__SyanMacro_Atom>, Vec<Param>: Parse<__SyanMacro_Atom>, DefEqTok: Parse<__SyanMacro_Atom>, ExprErasedV1: Parse<__SyanMacro_Atom>,

type Error = ParseError<<__SyanMacro_Atom as Spanned>::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<__SyanMacro_S: ParseStream<Atom = __SyanMacro_Atom>>( __syan_stream: &mut __SyanMacro_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 RecClauseV1

fn eq(&self, other: &RecClauseV1) -> bool

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for RecClauseV1

impl<__SyanMacro_Atom> Unparse<__SyanMacro_Atom> for RecClauseV1

where BindName: Unparse<__SyanMacro_Atom>, Vec<Param>: Unparse<__SyanMacro_Atom>, DefEqTok: Unparse<__SyanMacro_Atom>, ExprErasedV1: Unparse<__SyanMacro_Atom>,

fn unparse<__Syan_Emitter: Emitter<__SyanMacro_Atom>>( &self, __syan_sink: &mut __Syan_Emitter, ) -> Result<(), <__Syan_Emitter as Emitter<__SyanMacro_Atom>>::Error>
