Module Std_kernel.Info

module Info: Info

type t 
Serialization and comparison force the lazy message.
include Invariant_intf.S
val to_string_hum : t -> string
to_string_hum forces the lazy message, which might be an expensive operation.

to_string_hum usually produces a sexp; however, it is guaranteed that to_string_hum (of_string s) = s.

If this string is going to go into a log file, you may find it useful to ensure that the string is only one line long. To do this, use to_string_mach t.

val to_string_mach : t -> string
to_string_mach t outputs t as a sexp on a single-line.
val to_string_hum_deprecated : t -> string
old version (pre 109.61) of to_string_hum that some applications rely on.

Calls should be replaced with to_string_mach t, which outputs more parenthesis and backslashes.

val of_string : string -> t
val of_lazy : string Lazy.t -> t
Be careful that the body of the lazy or thunk does not access mutable data, since it will only be called at an undetermined later point.
val of_thunk : (unit -> string) -> t
val create : ?here:Source_code_position0.t ->
?strict:unit -> string -> 'a -> ('a -> Sexplib.Sexp.t) -> t
For create message a sexp_of_a, sexp_of_a a is lazily computed, when the info is converted to a sexp. So, if a is mutated in the time between the call to create and the sexp conversion, those mutations will be reflected in the sexp. Use ~strict:() to force sexp_of_a a to be computed immediately.
val createf : ('a, unit, string, t) Pervasives.format4 -> 'a
Construct a t containing only a string from a format. This eagerly constructs the string.
val tag : t -> string -> t
Add a string to the front.
val tag_arg : t -> string -> 'a -> ('a -> Sexplib.Sexp.t) -> t
Add a string and some other data in the form of an s-expression at the front.
val of_list : ?trunc_after:int -> t list -> t
Combine multiple infos into one
val of_exn : ?backtrace:[ `Get | `This of string ] -> exn -> t
of_exn and to_exn are primarily used with Error, but their definitions have to be here because they refer to the underlying representation.
val to_exn : t -> exn
val pp : Format.formatter -> t -> unit

of_exn and to_exn are primarily used with Error, but their definitions have to be here because they refer to the underlying representation.

Info.t is wire-compatible with V2.t, but not V1.t. V1 bin-prots a sexp of the underlying message, whereas V2 bin-prots the underlying message.
