      Header elaboration data of a DefView.

      • shortDeclName : Lake.Name

        Short name. Recall that all declarations in Lean 4 are potentially recursive. We use shortDeclName to refer to them at valueStx, and other declarations in the same mutual block.

      • declName : Lake.Name

        Full name for this declaration. This is the name that will be added to the Environment.

      • levelNames : List Lake.Name

        Universe level parameter names explicitly provided by the user.

      • binderIds : Array Lean.Syntax

        Syntax objects for the binders occurring before :, we use them to populate the InfoTree when elaborating valueStx.

      • numParams : Nat

        Number of parameters before :, it also includes auto-implicit parameters automatically added by Lean.

      • type : Lean.Expr

        Type including parameters.
