type log_threshold = [ `All | `Src of string ] * Logs.level
The type for log threshold.
val set_level : default:Logs.level -> log_threshold list -> unit
set_level ~default l
set the log levels needed to have all of the log sources appearing in l
be used.
module Arg : sig ... end
include module type of Functoria_runtime with module Arg := Arg
module Key : sig ... end
Key
defines values that can be set by runtime command-line arguments. This module is the runtime companion of Functoria_key
.
val with_argv : unit Cmdliner.Term.t list -> string -> string array -> unit
with_argv keys name argv
evaluates the keys
terms on the command-line argv
. name
is the executable name. On evaluation error the application calls exit(3)
with status 64
. If `Help
or `Version
were evaluated, exit(3)
is called with status 63
.
val at_exit : (unit -> unit Lwt.t) -> unit
at_exit hook
registers hook
, which will be executed before the unikernel exits. The first hook registered will be executed last.
at_enter_iter hook
registers hook
to be executed at the beginning of each event loop iteration. The first hook registered will be executed last.
If hook
calls at_enter_iter
recursively, the new hook will run only on the next event loop iteration.
at_leave_iter hook
registers hook
to be executed at the end of each event loop iteration. See at_enter_iter
for details.
This is mainly for for developers implementing new targets.
val run_exit_hooks : unit -> unit Lwt.t
run_exit_hooks ()
calls the sequence of hooks registered with at_exit
in sequence.
run_enter_iter_hooks ()
calls the sequence of hooks registered with at_enter_iter
in sequence.
run_leave_iter_hooks ()
call the sequence of hooks registered with at_leave_iter
in sequence.
