Module `Ecaml_value.Function`

Lower-level interface for functions that call from Emacs to OCaml.

Try Defun first.

module Fn : sig ... end

include Value.Subtype

type value
type t = private value: We expose private value for free identity conversions when the value is nested in some covariant type, e.g. (symbols : Symbol.t list :> Value.t list) rather than List.map symbols ~f:Symbol.to_value.

val sexp_of_t : t -> Ppx_sexp_conv_lib.Sexp.t

val eq : t -> t -> bool: eq t1 t2 = Value.eq (to_value t1) (to_value t2), i.e. eq checks whether the Emacs values underlying t1 and t2 are physically equal. This is different than phys_equal t1 t2, because we don't always wrap eq Emacs values in phys_equal OCaml values. I.e. phys_equal t1 t2 implies eq t1 t2, but not the converse.
