val finalise : ('a -> 'b) -> (unit -> 'a) -> 'a

Finaliser for a function that returns a result and doesn't raise exceptions.

If the finaliser fails, it is recommended to log the error.

val finalise_exn : ('a option -> 'b) -> (unit -> 'a) -> 'a

Finaliser for a function that might raise exceptions.

base_error is the type of most errors that can occur in a result, except for errors that have associated exceptions (see below) and backend-specific errors (see Io_errors).
