Module Info


include Info_intf.S
type t

Serialization and comparison force the lazy message.

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 create_s : Sexplib.Sexp.t -> t
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
