Module `Dcalc.Typing`Source

Typing for the default calculus. Because of the error terms, we perform type inference using the classical W algorithm with union-find unification.

val infer_types : 
  Ast.decl_ctx ->
  Ast.untyped Ast.marked_expr ->
  Ast.typed Ast.marked_expr Bindlib.box

Infers types everywhere on the given expression, and adds (or replaces) type annotations on each node

Sourceval infer_type : Ast.decl_ctx -> 'm Ast.marked_expr -> Ast.typ Utils.Marked.pos

Gets the outer type of the given expression, using either the existing annotations or inference

val check_type : 
  Ast.decl_ctx ->
  'm Ast.marked_expr ->
  Ast.typ Utils.Marked.pos ->
  unit

Sourceval infer_types_program : Ast.untyped Ast.program -> Ast.typed Ast.program
