Function rapid_positioning 

pub fn rapid_positioning<'a, I: Iterator<Item = Field<'a>>>(
    args: I,
) -> Command<'a>

Moves the head to the desired position at the fastest possible speed.

NEVER enter a cut with rapid positioning. Some older machines may “dog leg” rapid positioning, moving one axis at a time

To instantiate the command, call this function or use the crate::command macro.
