Struct ucglib::ast::FuncDef

pub struct FuncDef {
    pub scope: Option<Scope>,
    pub argdefs: Vec<PositionedItem<String>>,
    pub fields: Box<Expression>,
    pub pos: Position,
}

Encodes a func expression in the UCG AST..

A func is a pure function over a tuple.

Fields

scope: Option<Scope>

argdefs: Vec<PositionedItem<String>>

fields: Box<Expression>

pos: Position
