Module Exn_string

The point of this module is to be able to include an exn in a type that has to be sexpable or binable. The Exn_string.t type is more descriptive than just converting to a string and is guaranteed to have come from an exn (unless someone abuses the t_of_sexp function or something).

Signature

type t = private string
include Core.Std.Sexpable with type t := t
type t
val t_of_sexp : Sexplib.Sexp.t -> t
val sexp_of_t : t -> Sexplib.Sexp.t
include Core.Std.Stringable with type t := t
type t
val of_string : string -> t
val to_string : t -> string
include Core.Std.Binable with type t := t
type t
val bin_size_t : t Bin_prot.Size.sizer
val bin_write_t : t Bin_prot.Write.writer
val bin_read_t : t Bin_prot.Read.reader
val __bin_read_t__ : (int -> t) Bin_prot.Read.reader

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.

val bin_writer_t : t Bin_prot.Type_class.writer
val bin_reader_t : t Bin_prot.Type_class.reader
val bin_t : t Bin_prot.Type_class.t
val of_exn : exn -> t
