func DeepSize ¶
func DeepSize(x interface{}) (numBytes int)
DeepSize estimates the amount of memory used by a Go value. It's intended as a memory usage debugging aid. Argument must be a pointer to a value.
Not thread safe. Behavior is undefined if any value reachable from the argument is concurrently mutated. In general, do not call this in production.
Behavior: * Recursively descends into contained values (struct fields, slice elements, etc.), tracking visitation (by memory address) to handle cycles. * Only counts slice length, not unused capacity. * Only counts map key and value size, not map overhead. * Does not count functions or channels.
The implementation relies on the Go garbage collector being non-compacting (not moving values in memory), due to thread non-safety noted above. This is true as of Go 1.13, but could change in the future.
