\usage{
memoryCache(
  max_size = 200 * 1024^2,
  max_age = Inf,
  max_n = Inf,
  evict = c("lru", "fifo"),
  missing = key_missing(),
  exec_missing = deprecated(),
  logfile = NULL
)
}
\arguments{
\item{max_size}{Maximum size of the cache, in bytes. If the cache exceeds
this size, cached objects will be removed according to the value of the
\code{evict}. Use \code{Inf} for no size limit. The default is 512 megabytes.}

\item{max_age}{Maximum age of files in cache before they are evicted, in
seconds. Use \code{Inf} for no age limit.}

\item{max_n}{Maximum number of objects in the cache. If the number of objects
exceeds this value, then cached objects will be removed according to the
value of \code{evict}. Use \code{Inf} for no limit of number of items.}

\item{evict}{The eviction policy to use to decide which objects are removed
when a cache pruning occurs. Currently, \code{"lru"} and \code{"fifo"} are supported.}

\item{missing}{A value to return when \code{get(key)} is called but the key is not
present in the cache. The default is a \code{\link[cachem:key_missing]{key_missing()}} object. It is
actually an expression that is evaluated each time there is a cache miss.
See section Missing keys for more information.}

\item{exec_missing}{Deprecated.}

\item{logfile}{An optional filename or connection object to where logging
information will be written. To log to the console, use \code{stderr()} or
\code{stdout()}.}
