NAME
       CHI::Driver::Memory - In-process memory based cache

VERSION
       version 0.54

SYNOPSIS
	   use CHI;

	   my $hash = {};
	   my $cache = CHI->new( driver => 'Memory', datastore => $hash );

	   my $cache = CHI->new( driver => 'Memory', global => 1 );

DESCRIPTION
       This cache driver stores data on a per-process basis.  This is the fastest of the cache implementations, but data can not be shared between
       processes.  Data will remain in the cache until cleared, expired, or the process dies.

       To maintain the same semantics as other caches, references to data structures are deep-copied on set and get. Thus, modifications to the
       original data structure will not affect the data structure stored in the cache, and vica versa. See CHI::Driver::RawMemory for a faster
       memory cache that sacrifices this behavior.

CONSTRUCTOR OPTIONS
       When using this driver, the following options can be passed to CHI->new() in addition to the CHI. One of datastore or global must be
       specified, or else a warning (possibly an error eventually) will be thrown.

       datastore [HASHREF]
	   A reference to a hash to be used for storage. Within the hash, each namespace is used as a key to a second-level hash.  This hash may
	   be passed to multiple CHI::Driver::Memory constructors.

       global [BOOL]
	   Use a standard global datastore. Multiple caches created with this flag will see the same data. Before 0.21, this was the default
	   behavior; now it must be specified explicitly (to avoid accidentally sharing the same datastore in unrelated code).

DISCARD POLICY
       For CHI/SIZE AWARENESS caches, this driver implements an 'LRU' policy, which discards the least recently used items first. This is the
       default policy.
