Create the url
argument of tar_resources()
to specify optional settings for URL storage formats.
See the format
argument of tar_target()
for details.
Arguments
- handle
Object returned by
curl::new_handle
orNULL
.
Value
Object of class "tar_resources_url"
, to be supplied
to the url argument of tar_resources()
.
Resources
Functions tar_target()
and tar_option_set()
each takes an optional resources
argument to supply
non-default settings of various optional backends for data storage
and high-performance computing. The tar_resources()
function
is a helper to supply those settings in the correct manner.
Resources are all-or-nothing: if you specify any resources
with tar_target()
, all the resources from tar_option_get("resources")
are dropped for that target. In other words, if you write
tar_option_set(resources = resources_1)
and then
tar_target(x, my_command(), resources = resources_2)
, then everything
in resources_1
is discarded for target x
.
