Struct RecordKind 

pub struct RecordKind {
    pub rec: RecordGroup<()>,
    pub fields: Vec<RecordKindField>,
}

kxtop: (| l1 : ty1; … |), a record-kind bound — “the constrained type variable must be a record containing at least these labels” (upstream MRecordKind; lowers to this port’s Kind::Record row obligation, presence-only — see typecheck.rs).

Fields

rec: RecordGroup<()>

fields: Vec<RecordKindField>

Trait Implementations

impl Clone for RecordKind

fn clone(&self) -> RecordKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecordKind

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

Formats the value using the given formatter.

impl<__SyanMacro_Atom> Parse<__SyanMacro_Atom> for RecordKind

where __SyanMacro_Atom: Spanned + Clone, RecordGroup<()>: GroupShape<__SyanMacro_Atom>, __SyanSubstructOfOwn_rec_RecordKind_3378190807597211705: 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 RecordKind

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for RecordKind

impl<__SyanMacro_Atom> Unparse<__SyanMacro_Atom> for RecordKind

where RecordGroup<()>: GroupUnparse<__SyanMacro_Atom>, for<'syan_substruct_ref> __SyanSubstructOfRef_rec_RecordKind_17770240377376662608<'syan_substruct_ref>: Unparse<__SyanMacro_Atom>,

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