impl Eq for DefaultTypes

impl Fold<DefaultTypes> for Bubbler

type Error = Infallible

fn fold_annotation( &mut self, anno: <DefaultTypes as AstTypes>::Annotation, ) -> Result<<DefaultTypes as AstTypes>::Annotation, Self::Error>

Consumes an Annotation in A, possibly transforms it, and produces a replacement Annotation in B

fn fold_macro_id( &mut self, name: <DefaultTypes as AstTypes>::MacroId, ) -> Result<<DefaultTypes as AstTypes>::MacroId, Self::Error>

Consumes a MacroId in A, possibly transforms it, and produces a replacement MacroId in B

fn fold_symbol( &mut self, name: <DefaultTypes as AstTypes>::Symbol, ) -> Result<<DefaultTypes as AstTypes>::Symbol, Self::Error>

Consumes a Symbol in A, possibly transforms it, and produces a replacement Symbol in B

fn fold_path( &mut self, path: <DefaultTypes as AstTypes>::Path, ) -> Result<<DefaultTypes as AstTypes>::Path, Self::Error>

Consumes a Path in A, possibly transforms it, and produces a replacement Path in B

fn fold_literal( &mut self, lit: <DefaultTypes as AstTypes>::Literal, ) -> Result<<DefaultTypes as AstTypes>::Literal, Self::Error>

Consumes a Literal in A, possibly transforms it, and produces a replacement Literal in B

fn fold_at_pat( &mut self, pat: At<Pat<DefaultTypes>, DefaultTypes>, ) -> Result<At<Pat<DefaultTypes>, DefaultTypes>, Self::Error>

Folds an annotated pattern, so the pattern and annotation can be seen at once.

fn fold_bind( &mut self, bind: Bind<DefaultTypes>, ) -> Result<Bind<DefaultTypes>, Self::Error>

Consumes a Bind, possibly transforms it, and produces a replacement Bind

fn fold_at_expr( &mut self, expr: At<Expr<From>, From>, ) -> Result<At<Expr<To>, To>, Self::Error>

Folds an annotated expression, so the expression and annotation can be seen at once.

fn fold_expr(&mut self, expr: Expr<From>) -> Result<Expr<To>, Self::Error>

Consumes an Expr, possibly transforms it, and produces a replacement Expr

fn fold_use(&mut self, item: Use<From>) -> Result<Use<To>, Self::Error>

Consumes a Use, possibly transforms it, and produces a replacement Use

fn fold_pat(&mut self, pat: Pat<From>) -> Result<Pat<To>, Self::Error>

Consumes a Pat, possibly transforms it, and produces a replacement Pat

fn fold_make(&mut self, make: Make<From>) -> Result<Make<To>, Self::Error>

Consumes a Make, possibly transforms it, and produces a replacement Make

fn fold_makearm( &mut self, arm: MakeArm<From>, ) -> Result<MakeArm<To>, Self::Error>

Consumes a MakeArm, possibly transforms it, and produces a replacement MakeArm

fn fold_match(&mut self, mtch: Match<From>) -> Result<Match<To>, Self::Error>

Consumes a Make, possibly transforms it, and produces a replacement Make

fn fold_matcharm( &mut self, arm: MatchArm<From>, ) -> Result<MatchArm<To>, Self::Error>

Consumes a MakeArm, possibly transforms it, and produces a replacement MakeArm

impl Hash for DefaultTypes

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DefaultTypes

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
