This include is the source of the bin_io functions.

Error.t is not wire-compatible with Error.Stable.V1.t. See info.mli for details.

val failwiths : ?strict:Base.Unit.t -> ?here:Stdlib.Lexing.position -> Base.String.t -> 'a -> ('a -> Base.Sexp.t) -> _
failwiths ?strict ?here message a sexp_of_a
= Error.raise (Error.create ?strict ?here s a sexp_of_a)

As with Error.create, sexp_of_a a is lazily computed when the error is converted to a sexp. So if a is mutated in the time between the call to failwiths and the sexp conversion, those mutations will be reflected in the error message. Use ~strict:() to force sexp_of_a a to be computed immediately.

The pa_fail preprocessor replaces failwiths with failwiths ?here:[%here] so that one does not need to (and cannot) supply [%here]. pa_fail does not add ?here:[%here] to Error.failwiths.

In this signature we write ?here:Lexing.position rather than ?here:Source_code_position.t to avoid a circular dependency.

failwithp here is like failwiths ~here, except that you can provide a source position yourself (which is only interesting if you don't provide [%here]).

val failwithp : ?strict:Base.Unit.t -> Stdlib.Lexing.position -> Base.String.t -> 'a -> ('a -> Base.Sexp.t) -> _
