my $cache = Dezi::Bot::Cache->new(%chi_params);
$cache->add( foo => 'bar' );

DESCRIPTION

The Dezi::Bot::Cache module conforms to the SWISH::Prog::Cache API but delegates all caching to CHI.

METHODS

new( chi_params )

Returns instance of Dezi::Bot::Cache, initializing the internal CHI object with chi_params.

If empty, chi_params defaults to:

%chi_params = (
  driver    => 'File',
  root_dir  => '/tmp/dezibot',
  namespace => 'dezibot',
);

chi

Returns the internal CHI object.

add( key, value [, expires] )

Add key value pair to cache, optional expires setting. See CHI for expires documentation.

has( key )

Returns true if key is in the cache and has not expired.

get( key )

Returns value for key or undef if key is not present or has expired.

delete( key )
