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 avail-
able, 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 com-
piled with debug information ( -g )
Since 4.02
val name : t -> string option
name slot returns the name of the function or definition enclosing the
location referred to by the slot.
name slot returns None if the name is unavailable, which may happen for
the same reasons as location returning None.
Since 4.11
val format : int -> t -> string option
format pos slot returns the string representation of slot as raw_back-
trace_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
