A rudimentary export format, adapted from https://github.com/leanprover-community/lean/blob/master/doc/export_format.md with support for lean 4 kernel primitives.

inductive Lean.Export.Entry : Type

• name (n : Name) : Entry
• level (n : Level) : Entry
• expr (n : Expr) : Entry
• defn (n : Name) : Entry

instance Lean.Export.instInhabitedEntry : Inhabited Entry

instance Lean.Export.instCoeNameEntry : Coe Name Entry

instance Lean.Export.instCoeLevelEntry : Coe Level Entry

instance Lean.Export.instCoeExprEntry : Coe Expr Entry

structure Lean.Export.Alloc (α : Type u_1) [BEq α] [Hashable α] : Type u_1

• map : Std.HashMap α Nat
• next : Nat

instance Lean.Export.instInhabitedAlloc {a✝ : Type u_1} {a✝¹ : BEq a✝} {a✝² : Hashable a✝} : Inhabited (Alloc a✝)

structure Lean.Export.State : Type

• names : Alloc Name
• levels : Alloc Level
• exprs : Alloc Expr
• defs : Std.HashSet Name
• stk : Array (Bool × Entry)

instance Lean.Export.instInhabitedState : Inhabited State

class Lean.Export.OfState (α : Type) [BEq α] [Hashable α] : Type

• get : State → Alloc α
• modify : (Alloc α → Alloc α) → State → State

instance Lean.Export.instOfStateName : OfState Name

instance Lean.Export.instOfStateLevel : OfState Level

instance Lean.Export.instOfStateExpr : OfState Expr

@[reducible, inline]

abbrev Lean.ExportM (α : Type) : Type

def Lean.Export.alloc {α : Type} [BEq α] [Hashable α] [OfState α] (a : α) : ExportM Nat

def Lean.Export.exportName (n : Name) : ExportM Nat

def Lean.Export.exportLevel (L : Level) : ExportM Nat

def Lean.Export.biStr : BinderInfo → String

partial def Lean.Export.exportExpr (E : Expr) : ExportM Nat

partial def Lean.Export.exportDef (n : Name) : ExportM Unit

def Lean.Export.exportDef.insert (n : Name) : ExportM Unit

partial def Lean.Export.exportDef.defn (ty : String) (n : Name) (t e : Expr) (ls : List Name) : ExportM Unit

partial def Lean.Export.exportDef.axdef (ty : String) (n : Name) (t : Expr) (ls : List Name) : ExportM Unit

partial def Lean.Export.exportDef.ind : List Name → ExportM Unit

partial def Lean.Export.exportDef.indbody (ind : Name) (s : String) : ExportM String

def Lean.Export.runExportM {α : Type} (m : ExportM α) : CoreM α
