module Common: sig .. end
Basic types and definitions required throughout the system.
exception Bug of string
exception Finally of exn * exn
Raised when finalization after an exception failed, too.
The first exception argument is the one raised by the initial
function, the second exception the one raised by the finalizer.
val unimplemented : string -> 'a Or_error.t
type float
type
type
Handy types for marking things read-only and read-write. One should not expose
functions for converting between read_only/immutable/read_write because the private
types expose the subtyping. Users would say "(db :> read_only Db.t)" to cast. The
difference between read-only and immutable is that someone else can change a read-only
object, while immutable never changes.
type read_only
type read_only
type Never_returns.never_returns
never_returns should be used as the return type of functions that don't return and
might block forever, rather than 'a or _. This forces callers of such functions
to have a call to never_returns at the call site, which makes it clear to readers
what's going on. We do not intend to use this type for functions such as failwithf
that always raise an exception.

val ident : 'a -> 'a

val (==>) : bool -> bool -> bool

A comparator that returns results in ascending order.
A comparator that returns results in descending order.
