Method: External::Io#copy

Defined in:
lib/external/io.rb

#copy(mode = "r", range = 0..length) ⇒ Object

– it appears that as long as the io opening t.path closes, the tempfile will be deleted at the exit of the ruby instance… otherwise it WILL NOT BE DELETED Make note of this in the documentation to be sure to close files if you start inserting because it may make tempfiles ++
