struct Options
When specifying a value, you can use only one of the options listed in Memory Options, only one of the options listed in Personality Options, and any number of other options.
These options are mutually exclusive.
static var machUse Mach memory.
static var mallocUse free() on removal, calloc() on copy in.
static var opaqueTake no action when pointers are deleted.
static var strongUse strong write-barriers to backing store; use garbage-collected memory on copy-in.
static var weakUses weak read and write barriers appropriate for ARC or GC. Using NSPointerFunctionsWeakMemory object references will turn to NULL on last release.
These options are mutually exclusive.
static var cUse a string hash and strcmp; C-string '%s' style description.
static var integerUse unshifted value as hash and equality.
static var objectUse hash and is methods for hashing and equality comparisons, use the description method for a description.
static var objectUse shifted pointer for the hash value and direct comparison to determine equality; use the description method for a description.
static var opaqueUse shifted pointer for the hash value and direct comparison to determine equality.
static var structUse a memory hash and memcmp (using a size function that you must set—see size).
static var copyUse the memory acquire function to allocate and copy items on input (see acquire).
let NSMapEquivalent to copy.
