# Method Debug.memory_usage()

Method memory_usage

  ``mapping`(`string`:`int`) memory_usage()`

Description

  Check memory usage.

  This function is mostly intended for debugging. It delivers a mapping with information about how many arrays/mappings/strings etc. there are currently allocated and how much memory they use.

  The entries in the mapping are typically paired, with one named `"num_" + SYMBOL + "s"` containing a count, and the other named `SYMBOL + "_bytes"` containing a best effort approximation of the size in bytes.

Note

  Exactly what fields this function returns is version dependant.
