Variants

Nil

Bool(bool)

Number(f64)

String(RcStr)

Name(RcStr)

List(Vec<Expr>)

Map(Vec<(Expr, Expr)>)

Parentheses(Box<Expr>)

Block(Vec<Expr>)

Switch(Box<Expr>, Vec<(Expr, Expr)>, Option<Box<Expr>>)

If(Vec<(Expr, Expr)>, Option<Box<Expr>>)

For(AssignTarget, Box<Expr>, Box<Expr>)

While(Box<Expr>, Box<Expr>)

Binop(Binop, Box<Expr>, Box<Expr>)

LogicalBinop(LogicalBinop, Box<Expr>, Box<Expr>)

Unop(Unop, Box<Expr>)

Subscript(Box<Expr>, Box<Expr>)

Slice(Box<Expr>, Option<Box<Expr>>, Option<Box<Expr>>)

Attr(Box<Expr>, RcStr)

CallFunction(Box<Expr>, Args)

CallMethod(Box<Expr>, RcStr, Args)

Assign(AssignTarget, Box<Expr>)

AugAssign(AssignTarget, Binop, Box<Expr>)

NonlocalAssign(RcStr, Box<Expr>)

Nonlocal(Vec<RcStr>)

New(Option<RcStr>, Vec<(RcStr, Expr)>)

Del(RcStr)

Yield(Box<Expr>)

Return(Option<Box<Expr>>)

Import(RcStr)

BreakPoint

AssignDoc(Box<Expr>, RcStr, RcStr)

AssignDoc at runtime is more or less a nop. However, it attaches docstrings to field assignments (the first ‘Expr’ parameter should always be an Assign)

Function

Fields

is_generator: bool

name: Option<RcStr>

params: ArgSpec

docstr: Option<RcStr>

body: Box<Expr>

varspec: Option<VarSpec>

Class

Fields

name: RcStr

bases: Vec<Expr>

docstr: Option<RcStr>

methods: Vec<(RcStr, Expr)>

static_methods: Vec<(RcStr, Expr)>

hidden_name: Option<RcStr>

The hidden name for a class is computed during annotation. The hidden name is used by methods to refer to the class that they belong to
