Fast but transient environment driver. This driver saves objects in a local R environment, without serialisation. This makes lookup fast but it cannot be saved across sesssions. The environment storr can be made persistent by saving it out as a file storr though.
storr_environment(envir = NULL, hash_algorithm = NULL, default_namespace = "objects") driver_environment(envir = NULL, hash_algorithm = NULL)
| envir | The environment to point the storr at. The default
creates an new empty environment which is generally the right
choice. However, if you want multiple environment storrs
pointing at the same environment then pass the |
