A whole 0.1 .saty/.satyh file (main, upstream parser_v1.mly:364- 368): a header list followed by either a library (main_lib) or a document expression. Unlike 0.0.6’s crate::cst::File (a flat prelude of top-level lets with an optional trailing in body), 0.1 has no flat top-level binding sequence at all: a document body is just an ast::Expr (every let chains its own in), and a library is exactly one module … = struct … end.

Variants

Document

header* expr EOI (parser_v1.mly:367).

Trait Implementations

impl Clone for FileV1

fn clone(&self) -> FileV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileV1

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

Formats the value using the given formatter.

impl<__SyanMacro_Atom> Parse<__SyanMacro_Atom> for FileV1

where __SyanMacro_Atom: Spanned + Clone, Vec<HeaderV1>: Parse<__SyanMacro_Atom>, Expr: Parse<__SyanMacro_Atom>, EoiTok: Parse<__SyanMacro_Atom>, KwModule: Parse<__SyanMacro_Atom>, CtorTok: Parse<__SyanMacro_Atom>, Option<SigAnnotV1>: Parse<__SyanMacro_Atom>, DefEqTok: Parse<__SyanMacro_Atom>, KwStruct: Parse<__SyanMacro_Atom>, Vec<Bind>: Parse<__SyanMacro_Atom>, KwEnd: 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 FileV1

fn eq(&self, other: &FileV1) -> bool

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for FileV1

impl<__SyanMacro_Atom> Unparse<__SyanMacro_Atom> for FileV1

where Vec<HeaderV1>: Unparse<__SyanMacro_Atom>, Expr: Unparse<__SyanMacro_Atom>, EoiTok: Unparse<__SyanMacro_Atom>, KwModule: Unparse<__SyanMacro_Atom>, CtorTok: Unparse<__SyanMacro_Atom>, Option<SigAnnotV1>: Unparse<__SyanMacro_Atom>, DefEqTok: Unparse<__SyanMacro_Atom>, KwStruct: Unparse<__SyanMacro_Atom>, Vec<Bind>: Unparse<__SyanMacro_Atom>, KwEnd: Unparse<__SyanMacro_Atom>,

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