pub struct RangeFrom<Idx> {
pub start: Idx,
}
A range which is only bounded below.
Fields
start | The lower bound of the range (inclusive).
|
Methods
Unstable (step_by
): recent addition
Creates an iterator starting at the same point, but stepping by
the given amount at each iteration.
for i in (0u8..).step_by(2).take(10) {
println!("{}", i);
}
This prints the first ten even natural integers (0 to 18).
