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 create : ?here:Base__.Source_code_position0.t ‑> ?strict:unit ‑> string ‑> 'a ‑> ('a ‑> 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 : 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 ‑> tag:string ‑> t

Add a string to the front.

val tag_arg : t ‑> string ‑> 'a ‑> ('a ‑> 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
