PR, or “Parser Representation” is an AST representation of parsed PRQL. It takes LR tokens and converts them into a more structured form which understands expressions, such as tuples & functions.

Re-exports

• pub use crate::span::Span;

Structs

• Annotation
• BinaryExpr
  Expression with two operands and an operator, such as 1 + 2.
• Expr
  Expr is anything that has a value and thus a type. Most of these can contain other Expr themselves; literals should be ExprKind::Literal.
• Func
  Function called with possibly missing positional arguments. May also contain environment that is needed to evaluate the body.
• FuncCall
  Function call.
• FuncParam
• GenericTypeParam
• Ident
  A name. Generally columns, tables, functions, variables. This is glorified way of writing a “vec with at least one element”.
• ImportDef
• ModuleDef
• Pipeline
  A value and a series of functions that are to be applied to that value one after another.
• QueryDef
• Stmt
• Ty
• TyFunc
• TypeDef
• UnaryExpr
  Expression with one operand and an operator, such as -1.
• VarDef
