type t = | Alloc of {obj_id : Obj_id.t;(*An identifier for this allocation, used to refer to it in other events. These identifiers are generated in allocation order.
*)length : int;(*Length of the sampled allocation, in words, not including header word
*)nsamples : int;(*Number of samples made in this allocation. At least 1.
*)is_major : bool;(*Whether this object was initially allocated on the major heap
*)backtrace_buffer : Location_code.t array;(*Backtrace of the allocation. The backtrace elements are stored in order from caller to callee. The first element is the main entrypoint and the last is the allocation.
NB: this is a mutable buffer, reused between events. Entries at indices beyond
*)backtrace_length - 1are not meaningful. If you want to store backtraces, you must copy them using:Array.sub backtrace_buffer 0 backtrace_length.backtrace_length : int;(*Length of the backtrace
*)common_prefix : int;(*A prefix of this length has not changed since the last event
*)
