Module Ecaml.Var

An 'a Var.t is a symbol that holds values of type 'a, embedded in Elisp's Value.t via an 'a Type.t.

type 'a t = {
symbol : Symbol.t;
type_ : 'a Ecaml__.Import0.Value.Type.t;
}
val type_ : 'a t -> 'a Ecaml__.Import0.Value.Type.t
val symbol : 'a t -> Symbol.t
module Fields : sig ... end
val sexp_of_t : ('a -> Ppx_sexp_conv_lib.Sexp.t) -> 'a t -> Ppx_sexp_conv_lib.Sexp.t
type 'a var := 'a t
val create : Symbol.t -> 'a Ecaml__.Import0.Value.Type.t -> 'a t
module Wrap : sig ... end

Idiomatic usage of Wrap looks like:

module And_value : sig ... end
module And_value_option : sig ... end
val symbol_as_value : _ t -> Ecaml__.Import0.Value.t
val default_value_exn : 'a t -> 'a

val is_buffer_local_always : _ t -> bool

is_buffer_local_always t returns true if t automatically becomes buffer-local when set. Calling make_buffer_local_always t causes is_buffer_local_always t = true.
