Processing CSV inputs using regular expression

Suppose we have an input CSV file of http method and URL, this could be used to make parallel calls with curl. Here {method} and {url} are named regular expression capture groups:

$ cat >./test.csv <<EOL
GET,http://example.com/endpoint1
PUT,http://example.com/endpoint2
POST,http://example.com/endpoint3
EOL

$ cat test | rust-parallel -r '(?P<method>.*),(?P<url>.*)' curl -X {method} {url}
