type 'a no_raise = 'a

no_raise is the identity, but by using 'a no_raise in a sexpable type, the resulting use sexp_of_no_raise protects the conversion of 'a to a sexp so that if it fails, one gets a sexp with an error message about the failure, rather than an exception being raised.

WARNING: The resulting no_raise_of_sexp can still raise.

module Sexp_maybe : sig ... end

If sexp_of_t fails, it returns Error rather than raising. You can convert values of this type to and from sexp in processes that can or cannot parse the underlying sexp in any combination and still recover the original value. Also, the Error case contains a human-readable description of the error.

module With_text : sig ... end

A With_text.t is a value paired with the full textual representation of its sexp. This is useful for dealing with the case where you want to keep track of a value along with the format of the s-expression it was generated from, which allows you to maintain formatting details, comments, etc.

val of_sexp_allow_extra_fields_recursively : (Base.Sexp.t -> 'a) -> Base.Sexp.t -> 'a

of_sexp_allow_extra_fields_recursively of_sexp sexp uses of_sexp to convert sexp to a value, but will not fail if there are any extra fields in a record (even deeply nested records).

The implementation uses global state, so it is not thread safe.
