Module Slot
: sig end
Since 4.02.0
type t = Printexc.backtrace_slot
val is_raise : t -> bool
is_raise slot is true when slot refers to a raising point in the code, and false when it comes from a simple function call.
Since 4.02
val is_inline : t -> bool
is_inline slot is true when slot refers to a call that got inlined by the compiler, and false when it comes from any other context.
Since 4.04.0
val location : t -> Printexc.location option
location slot returns the location information of the slot, if available, and None otherwise.
Some possible reasons for failing to return a location are as follow:
-the slot corresponds to a compiler-inserted raise
-the slot corresponds to a part of the program that has not been compiled with debug information ( -g )
Since 4.02
val format : int -> t -> string option
format pos slot returns the string representation of slot as raw_backtrace_to_string would format it, assuming it is the pos -th element of the backtrace: the 0 -th element is pretty-printed differently than the others.
Whole-backtrace printing functions also skip some uninformative slots; in that case, format pos slot returns None .
Since 4.02
