Module Core__Syscall_result.Int

type ok_value
type 'a syscall_result
type t = ok_value syscall_result
include sig ... end
val sexp_of_t : t ‑> Sexplib.Sexp.t
val compare : t ‑> t ‑> int
val create_ok : ok_value ‑> t
val create_error : Core__.Unix_error.t ‑> t

val is_error : t ‑> bool
val to_result : t ‑> (ok_value, Core__.Unix_error.t) Core__.Import.Result.t

This returns a preallocated object for all errors and at least a few ok_values, so can be used in many contexts where avoiding allocation is important.

val ok_exn : t ‑> ok_value
val error_exn : t ‑> Core__.Unix_error.t
val reinterpret_error_exn : t ‑> _ syscall_result

This is more efficient than calling error_exn and then the create_error of the destination type.
